Hello Peter,

i would like to add to a multi bar chart a multi line chart which shows for each multipe bar the belonging line chart value.

When I add a new dataset for the multi line chart it creates me only a new line per "bar chart group".

Is it possible to also add a multi line chart to the multi bar chart?

Example:

a multi bar chart with 4 bars in four different groups = 16 Values

I would like to have also a multi line chart on the y2 axis for these 16 values (see attached screenshot)

Thanks
Volker

Peter,

here is also my sample code:


First I've created a multiple bar chart:

    $layer = $c->addBarLayer2(Side, 4);
    $data0 = array(1,2,3,4);
    $layer->addDataSet($data0, 0x1F497D, "Target 2013");
    $data0 = array(2,2,3,5);
    $layer->addDataSet($data1, 0x8DB4E2, "Actual 2013");

Then I've tried to add the beloning target values for each bar chart value as a line chart

$layer = $c->addLineLayer2(Side,4);
$plan_array = array(2,4,3,1);
$layer->addDataSet( $plan_array, 0xc00000, "EBIT 2013 in %");
$plan_array2 = array(3,4,5,2);
$layer->addDataSet( $plan_array2, 0xc00000, "ACTUAL EBIT 2013  in %");

Hi Volker,

May be you can try to use Layer.alignLayer. It is like:

#Bar layer as usual
$barLayer = $c->addBarLayer2(Side, 4);
$data0 = array(1,2,3,4);
$layer->addDataSet($data0, 0x1F497D, "Target 2013");
$data1 = array(2,2,3,5);
$layer->addDataSet($data1, 0x8DB4E2, "Actual 2013");

#The lines
$plan_array = array(2,4,3,1);
$layer = $c->addLineLayer($plan_array, 0xc00000, "EBIT 2013 in %");
$layer->alignLayer($barLayer, 0);  #align line with data set 0 of $barLayer
$plan_array2 = array(3,4,5,2);
$layer = $c->addLineLayer($plan_array2, 0xc00000, "ACTUAL EBIT 2013  in %");
$layer->alignLayer($barLayer, 1);  #align line with data set 1 of $barLayer

Hope this can help.

Regards
