Y axis values repeated

[laura]

Hi,

I have a problem with some plots because the Y axis values are repeated.

This is my source code:

$plot = new PHPlot(800, 600);

$data = array(array('',25,3.61,""),array('',25,"",4.41),array('',30,4.43,""),

array('',30,"",4.40),array('',35,4.41,""),array('',35,"",4.41));

$plot->SetDataType('data-data');

$plot->SetDataValues($data);

//Set titles

$plot->SetTitle("Example");

$plot->SetXTitle('x axis');

$plot->SetYTitle('y axis');

$plot->SetImageBorderType('plain');

// Set the backgrounds

$plot ->SetDrawPlotAreaBackground(1);

$plot ->SetBackgroundColor("white");

//Define the plot option

$plot->SetPlotType('lines');

//No 3-D shading of the bars:

$plot->SetShading(0);

//Line width

$plot->SetLineWidths(1);

//Turn off X tick labels and ticks because they don't apply here:

$plot->SetXTickPos('none');

// Format the Y Data Labels as numbers with 1 decimal place.

// Note that this automatically calls SetYLabelType('data').

$plot->SetPrecisionY(0);

$plot->SetXDataLabelPos('none');

$plot->SetXLabelType('data');

$plot->SetPrecisionX(0);

$plot->DrawGraph();

I can't put decimal values in the Y axis, because of that
$plot->SetPrecisionY(0), if I take off this instruction is working properly.
How can I do for not having the integers repeated? It's not always happening,
it depends on the data.

Many thanks in advance!

I think you will have to do one or more of these things:

1. Let the Y axis display decimals with e.g. SetPrecision(2). But you said you can't do this, although I'm not sure why.

2. Set a specific Y axis range with SetPlotAreaWorld(NULL, $ymin, NULL, $ymax) instead of letting PHPlot calculate it based on your data. You would pick a wider range.

3. Set either the Y tick increment (SetYTickIncrement(1)), or number of Y tick marks (SetNumYTicks(2)). This reduces the number of tick marks and labels on the Y axis, so they get labeled 3, 4, and 5.
