Error 25121 : Please help

[daniel.koe...@thermo-control.com]

Hello dear group!

I am getting desperately....

For a display of three lineplots I made the array with the respective data inside.

$maxError, $ValuesMes and $minError

print_r show the data nicely.

Array
(
    [0] => 0.6
    [1] => 0.6
    [2] => 0.6
    [3] => 0.6
    [4] => 0.7
    [5] => 0.8
    [6] => 0.9
    [7] => 1.1
    [8] => 1.2
    [9] => 1.3
)
Array
(
    [0] => 0.5
    [1] => 0.1
    [2] => 0.4
    [3] => 0.2
    [4] => 0.2
    [5] => 0.2
    [6] => 0.2
    [7] => 0.2
    [8] => 0.2
    [9] => 0.2
)
Array
(
    [0] => -0.6
    [1] => -0.6
    [2] => -0.6
    [3] => -0.6
    [4] => -0.7
    [5] => -0.8
    [6] => -0.9
    [7] => -1.1
    [8] => -1.2
    [9] => -1.3
)

However using this data for a

$lineplot1 = new LinePlot($maxError);

$graph -> add($lineplot1);

$graph->stroke();

I get the 25121 error.

Now, if I add manualy

$maxError[]=-2;

I get the image without any lines or points.

What am I doing wrong?  I have copied the varable names to prevent spelling mistakes .. no succsess



Any help is mostly appreciated!

Thank you, Daniel

Hi Daniel,

First, I would like to confirm your intention of declaring three variables $maxError, $ValuesMes, $minError?

I have tested the following code and got result as in the attached picture:

<?php // content="text/plain; charset=utf-8"

require_once ("jpgraph/jpgraph.php");

require_once ("jpgraph/jpgraph_line.php");

 

$maxError = array(0.6,0.6,0.6,0.6,0.7,0.8,0.9,1.1,1.2,1.3);

$ValuesMes = array(0.5,0.1,0.4,0.2,0.2,0.2,0.2,0.2,0.2,0.2);

$minError = array(-0.6,-0.6,-0.6,-0.6,-0.7,-0.8,-0.9,-1.1,-1.2,-1.3);

// Size of the overall graph

$width=350;

$height=250;

 

// Create the graph and set a scale.

// These two calls are always required

$graph = new Graph($width,$height);

$graph->SetScale('intlin');

 

// Create the linear plot

$lineplot=new LinePlot($maxError);

 

// Add the plot to the graph

$graph->Add($lineplot);

 

// Output graph

$graph->Stroke();
