 Resize Chart in respect to the legend-box? |

Hi guys,
I got some charts with dynamically generated content, so it is impossible for me to know
in advance how many datasets are added via "$layer->addDataSet()" and the legend can
quickly become larger than the chart-area, resulting in a cut-off legend-box.
Is there any way to instruct ChartDirector to compute the size of the legend-box and then
resize the chart in order to prevent legend entries from not being shown or being cut off?
Example is attached.
Thank you,
Chris

Hi Chris,
May be you can try something like (using ChartDirector Ver 5):
... create chart and add all data to the chart ....
$legendBox = $c->layoutLegend();
$c->setSize($c->getWidth(), $legendBox->getHeight() + 400);
Hope this can help.

Other possibility would be (since I embedded the charts into a website) to query the chart
something like "give me the colors and assigned legend item" so I could build a legend
myself using HTML. Does anyone know a method for it? |

Hi Chris,
Currently, the ChartDirector API is designed only to provide certain information created by ChartDirector (such as the legend box size). It does to provide information that your code already knows, such as the colors (as the colors are passed by your code to ChartDirector, so your code already knows the colors), and the data set names.
For your case, if you need to retrieve the colors, you would need to query your code for the colors and the data set names.
