Multiple X axis

[laura]

I would like to generate a plot with multiple X axis, I mean, I have these
values

x1 = 11, y1= 120

x2 = 15 , y2 = 145

where x1, y1 is one result, and have to be in one color, and x2, y2 is another
result with another color. I have 20 different values per each x1, y1, x2, y2

I'm not clear on what you are doing. If you want more than 1 X axis, with
different scales, then no PHPlot cannot do that. But a scatter-point (or
points plot) can have any number of (x,y) points. For each X, you can have
multiple Y, with each Y in a different color. By omitting all but one Y for
each X, I think you can do what you want.

Here is a script, using the number pairs from your email, just to see if this
is in any way what you are trying to do.

<?php

require_once 'phplot.php';

$data = array(

array('', 134, 150, ''),

array('', 180, 123, ''),

array('', 200, 190, ''),

array('', 120, '', 130),

array('', 190, '', 110),

array('', 100, '', 210),

);

$plot = new PHPlot(800, 600);

$plot->SetPlotType('points');

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

$plot->SetDataValues($data);

$plot->SetPlotAreaWorld(0, 0, 250, 250);

$plot->SetXTickIncrement(20);

$plot->SetYTickIncrement(20);

$plot->SetPointSizes(10);

$plot->DrawGraph();
