Have tried Call layer.setAggregateLabelStyle().setFontAngle(90) but that put the value on top og the bar.

Thanks

Hi Tony,

To put the label inside the bar, please use setDataLabelStyle instead of setAggregateLabelStyle. For example:

Call layer.setDataLabelStyle().setFontAngle(90)

Note that by default, if the length of the bar is too short to display the label, the label will not be displayed. If you want to force the label to display, please use BarLayer.setMinLabelSize. For example:

Call layer.setMinLabelSize(0)

Hope this can help.

Regards
Peter Kwan

Thanks Peter, It's worked when I remove some other code before this line.

I also tried to center the text and put a unit after the value.
Call layer.setDataLabelStyle("{label} kwh" ).setFontAngle(90)) (Can't see the value + kwh)
I tried to implement setAlignment(cd.Center) without any success.

Thanks
Tony

Hi Tony,

The setDataLabelStyle method, when called without all 4 arguments, sets the font angle to 0. (See the ChartDirector documentation on Layer.setDataLabelStyle for details.) The setFontAngle method then sets the font angle to 90.

The setDataLabelStyle method accepts a font name as the first argument. Since "{label} kwh" is probably not a font name, so its effect is to cause the data label to be drawn using the default font.

To set the label to be like "value + kwh", use:

Call layer.setDataLabelFormat("{value} kwh")

To change the text style (including alignment), please use setDataLabelStyle. For example:

Call layer.setDataLabelStyle("arial.ttf", 8, &H000000, 90).setAlignment(cd.Center)

or

Set t = layer.setDataLabelStyle()
Call t.setFontAngle(90)
Call t.setAlignment(cd.Center)

Hope this can help.
