Specifies the color for a series defined by its index in a chart.
void object->SetSeriesColor( int index, string color )
By default, a new data series added to a chart takes its colors from the chart style.
If the index argument refers to a series that does not exist in the chart object, the series is created.
The color argument can be specified:
As a named color.
Example: "orange"
For a complete reference of predefined named colors, consult
the Predefined Colors Reference.
Named colors are always opaque.
As a hexadecimal value "#RRGGBB", where RR, GG and BB represent the
hexadecimal values of the red, green and blue components.
Example: "#FFA500" represents an orange color.
An optional alpha component can be added at the end of the string: "#RRGGBBAA".
Example: "#FFA50080" represents a semi-transparent orange color,
"#FFA500FF" represents an opaque orange color,
"#FFA50000" represents an fully transparent (invisible) orange color.
When generating several charts using a single chart object, the ClearAll method can be used between each generated charts.
The following PHP code illustrates use of the SetSeriesColor method.
$values= array(); // Define the series #0 $values[0] = 10.5; $values[1] = 12.4; $values[2] = 15.9; $chart->SetSeriesValuesFromArray(0, $values); // Define the series #1 $values[0] = 13.1; $values[1] = 15.6; $values[2] = 19.2; $chart->SetSeriesValuesFromArray(1, $values); $chart->LoadStyle("column/Honolulu"); // Set the color of series #1 $chart->SetSeriesColor(1, "tomato"); $chart->ExportAsResponse();
