 Chart Legend Showing Symbols |

Hello,
In PHP I am making an arbitrary XY line chart. I do not want the symbol for a trend to show up on the actual chart, but I want it to appear in the Chart Legend, what is the best method?
$TotalLayerLabel = $c->addLineLayer($DataY,$Color,$TrendLabel);
$TotalLayerLabel->setXData($DataX);
$getDataSetObj = $TotalLayerLabel->getDataSet(0);
$getDataSetObj->setDataSymbol($Symbol,14);
I am passing an empty space as "$Symbol" so that no symbol appears on the chart trend, but I want this symbol to appear on my legend. |

Hi Rob,
If you would like a line without symbols to show on the chart, please add the line without the symbol.
If you would like a legend to contain a symbol but not displayed on the chart, please add a layer that contain the symbol but not displayed on the chart (eg. has no data).
For example:
#add a line that does not have the symbol and does not have the legend entry
$TotalLayerLabel = $c->addLineLayer($DataY,$Color,$TrendLabel);
$TotalLayerLabel->setXData($DataX);
$TotalLayerLabel->setLegendMode(NoLegend);
#add a layer that does not display on the chart but have a legend entry with a symbol
$LegendLayer = $c->addLineLayer(null,$Color,$TrendLabel);
$getDataSetObj = $LegendLayer->getDataSet(0);
$LegendLayer->setDataSymbol($Symbol,14);
Hope this can help.
Regards
Peter Kwan |
