Hi,

I am setting my xaxis labels like below:

my $textbox = $c->xAxis()->setLabels($labels);
$textbox->setFontStyle("LTYPEB.ttf");
$textbox->setFontSize(6);

But i need to rotate them 90 degrees so they fit on the graph without overwritting each other, is this possible.

Thanks
Ross

Also, is it possible to make the bars below the line a different color to the ones above the postive axis.

Cheers
Ross

Hi Ross,

To rotate the labels by 90 degrees, you may use:

$textbox->setFontAngle(90);

To make negative bars a different color, you may split the bars into 2 data sets, so they may have different colors. For an example, see "ChartDirector Documentation/XY Charts/Bar Charts/Positive Negative Bars".

Hope this can help.

Regards

I am having trouble translating this into my php code.

I have the following to create my x-axis labels (which are an array of values):

# Set x axis labels using the given labels
$c->xAxis->setLabels($labels);


I have tried different approaches with no luck including:

$c->xAxis->setLabels($labels)->setFontAngle(90); //does nothing

and

$c->xAxis->setFontAngle(90); // throws an error - Call to undefined method Axis::setFontAngle()


Any help is greatly appreciated.

Hi Bob,

The PHP syntax does not allow dereferencing a returned value from a function call (though this is allowed most other programming lanauges). You need to store the return value in a variable and dereference the variable. For example:

#This is illegal syntax in PHP
#$c->xAxis->setLabels($labels)->setFontAngle(90);

#This is legal syntax in PHP
$temp = $c->xAxis->setLabels($labels);
$temp->setFontAngle(90);

Hope this can help.

Hola yo tengo el mismo problema pero con PERL, PIERDO LA IMAGEN DE LA GRAFICA.

# Configure the bars within a group to touch each others (no gap)
$layer->setBarGap(0.2, $perlchartdir::TouchBar);

$ver= $c->xAxis->setLabels($labels);
$ver->setFontAngle(90);

# output the chart

my $chart1URL = $ver->makeTmpFile("/tmp/tmpcharts");
my $imageMap = $ver ->getHTMLImageMap("","","title='{dataSetName}@{xLabel}:{value|0}'");


Les agradecere enormemente su apoyo gracias.

Hi seafree,

The code in Perl should be:

$c->xAxis()->setLabels($labels)->setFontAngle(90);

You can also use:

my $ver= $c->xAxis()->setLabels($labels);
$ver->setFontAngle(90);

Hope this can help.

Hi seafree,

Is it possible that you have another line of code that changes the font angle back to 0 (eg.
a line that calls Axis.setLabelStyle)? Is it possible to inform me the complete charting part
of your code?
