Hi - I've moved PHPLOT development to https://github.com/ajRepo/phplot . Can you open support requests there instead?

Hello, support phplot release-6.2.0 PHP8? Currently I am using release-6.2.0 with PHP7.4. Thank you very much for your efforts. Greetings Michael

If you get the "image contains errors" error on your browser, it usually means there is text in what's returned in addition to the binary data that defines the image. So perhaps your dbc.php has some HTML header information that it is returning or the like. To tell - look at the raw data being returned for the image and see. Also - I've moved development to git via github ( https://github.com/AJRepo/PHPlot/ ) from Sourceforge.

every other php file on my site uses: include dbc.php; WHY does this break phplot? i have to get the actual sql connection line out of this file and put it in my graph.php manually, or i get the "image contains errors" every time. what am i doing wrong here?

I checked the php.ini file and the extension gd was commented out. Changed it and restarted and my graphs are now working. I would never have thought of that. Thanks for the help!

Is gd installed?

I just updated xampp to the latest version which include PHP 8.0.2. When I tried to run my line graph i didn't get the graph. When I tried it in a command line I got the following error below. I reloaded xampp that has php 7 and reissued the same command line the output.png was perfect. I'm not sure why the failure. Has anyone encountered this problem and is there a work around or fix?

Problem solved - seems the latested RasPi Buster comes with Mysql pre-installed and when you do the LAMP install as seen on the the web - FUBAR!.

Pre: a curl script collects information on my heating/cooling system and inserts into a mysql DB. A Phplot web script on a Fedora box runs fine.

That sounds like a kerning issue ( https://www.freetype.org/freetype2/docs/tutorial/step2.html ). So I would guess that - it is the differences between the Freetype setup that's causing that issue.

Hi, We're using phplot ver 6.2 on two significantly different versions of Mac OS (10.9 and 10.14). The Arial text font that we use renders differently on these two OS versions, though they both report using the same version of GD, (2.1.0 compatible). The effect is that both the character spacing and aspect ratio are different. The GD versionas reported by phpinfo(), and the truetype font files are the same, phpinfo() reports using different versions of Freetype, 2.3.11 versus 2.4.2. Does that explain...

lbayuk posted a comment on discussion Help and Discussion
Make sure you are using a TrueType font, e.g. with SetDefaultTTFont() and/or SetUseTTF(True). The built-in (non TrueType) GD fonts do not support what you are trying to do. Test with a hard-coded string, e.g. SetXTitle("Test Omega Ω") If you did (1), (2) works, but your code still does not work, you need to see exactly what MySQL is returning for that field. It should work with either the XML decimal numeric entity, or with the UTF-8 encoding of the character.

I am trying to put a greek Omega into the Y Axis Title. I'm following the PHPlot reference manual and its not working for me. Here's what I'm doing: I have a MySQL server. one of the fields is "YAxisTitle". so I use PHP to connect to the mySQL server, I find the record I want (out of 100ish). and pull the information from the fields, one of them is YAxisTitle. I use the Plot->SetYTitle ( mySQL_Result($datasource, 0, "YAxisTitle") but I can't get the Greek Letter Omega to come out. I used the examples...

Can someone give me some pointers on how to generate a file containing two charts overlayed. I can generate a file showing a single plot by passing a filename in the 'new PHPlot' declaration but can't work out how to do the same with multiple plots. Ultimately I need to generate a horizontal bar chart with error bars and the only way I can think of doing this is combining a horizontal bar chart with a horizontal error chart. Any other options I can use would also be very useful. Many thanks.

Should be straightforward 1) Set PHPlot to save the image (e.g. /tmp/my_phplot_output.png; ) (Look for SetOutputFile) 2) With FPDF $image1 = '/tmp/my_phplot_output.png'; // Insert a logo in the top-left corner $pdf->Image($image1,10,10); or 2) create a cell and put the image in it. //have a cell 40x40 with an image in it, no border, left aligned with text $this->Cell( 40, 40, $pdf->Image($image1, $pdf->GetX(), $pdf->GetY()), 0, 0, 'L', false );

Dear All, Issue resolved. For completeness sake the following resolved my issue. $plot->SetIsInline(true); $plot->SetOutputFile('file_name'); then you need to place it as an image. Regards and thank you
-
Dear Team, Can I ask whether it is possible to use the output of PHplot as an image to insert it in a pdf using fpdf? All examples that I have seen and tested are attributed to creation of plots as stand alone. What I require is to include phplots inside other content. The graphs have to be dynamically generated and then the resulting output be included in a report. Thanks for your assistance.

lbayuk, THANKS for the reply. I was able to get the log plot working based on your suggestion. The tick marks are still a problem. If I have some time--very unlikely anytime in the near future--maybe I'll dig into the phplot code and see if I fix this issue myself and then hand the fixed code over to y'all. Thanks again, James N
-
The message "expects integer, float given" is a little misleading. Normally the float given to imageline() is a whole number which gets silently converted to integer. In your case, mostly likely, the Y value is 0 or negative. For a log plot that gets you INF or NaN respectively, which cannot be converted to integer. Check your data. You probably have some Y <= 0.0. Can't do that with a log plot. As for tick marks, log plots have never been implemented that well. Very simple cases work OK but that's...

Hi, I hope I'm not treading on toes here... I found what I believe to be a bug (or at least a misfeature) in PHPlot, which I developed a fix for. I would like to (a) discuss whether this is indeed the appropriate fix, and if so (b) contribute it back to the community. The web site phplot.org refers to a repository on github, but there seems to be no activity and the code there seems to be identical to that here. The only active forum I've found is this one, so here goes... There are comments in the...

Further to my comment, I find the pie chart is rather "moody". It is not only the title, but I change the size a bit and it only shows that little picture from the browser not the pie chart. I add one thing in one pie chart, it works. I do the same thing in another pie chart and it disappears i. e. $product->SetImageBorderType('plain'); or changing $product->SetBackgroundColor('#ffffff'); to $product->SetBackgroundColor('#eeeeee'); or changing $product = new PHPlot(320,200); to $product = new PHPlot(330,200);...

Is there any other log I could check? Are there specific orders how to add the values?
-
no error - let's say that the title was "Title" and I changed it to "Titles" and whoop plot dissapears.
-
If the entire image disappears there may be an text error message returned which will cause the image to seem to disappear. Look in the logs for an error message - perhaps a comma missing, and.or look at the HTML source returned in that image to see if there's an error message.
-
Hi there, I have a really a strange issue of my pie chart not showing when I change the title of the chart. The titel is either in a variable $titel or in single quotes or double quotes. The values are correct because I can see the pie. Any idea how I can trouble shoot, avoid this please? Thank you, Slarti

the function json_encode just returns a string representation of the data. Try having $data as an array. Something like $data = array( array('Mon', 5), array('Tue', 15), array('Wed', 9), array('Thu', 9), array('Sat', 4), array('Sun', 1) ); See the docs ex-bars1.html for more info and multiple data per day e.g. $data = array( array('Mon',5,1), array('Tue',15,4), ... );

In attempoting to correct my output issue I have been trying to use json_encode() on the dataset resulting from my query. I can echo the data and it appears "correct" visually. But when I attempt to build a chart I get an error "Fatal error: SetDataValues(): Invalid data array (row 0) " I looked this up in the documentation and wasn;t sure of the underlying cause, but the comments referenced verison5.5 as having a fix. Here is what I have so far: $inc= $stmt->fetchAll(PDO::FETCH_ASSOC); $data = json_encode($inc);...

I am just starting with PHPlot. I have an application that would benefit greatly from adding charts to the reports currently being generated. First, I was looking for MySQL calls based on PDO. I have been able to pull data from my database using the fetchAll(PDO::FETCH_BOTH) command. But I am trying to build a stacked bar chart with days of the week as the x labels (text) and the sum of incidents (data) as the Y values. I was also trying to stack the values based on an incident code (text). The examples...
-
For the X-labels - yes you can print only a few labels. One way is to set the X-label to blank (e.g. '') for those you don't want displayed. See the example prune_labels.php For the Y-labels perhaps Custom Data Value Labeling is what you want. See the example: ex-dlexformat.html in the docs.

Since I have a lot of points in which the Y value remains the same and I also need to print all of my X labels (disregarding if the Y value has changed or not), I would like to know if there's a way to add a condition...
