I used the chart tool to create a stacked bar chart. I cannot figure out how to set the width of the bar with any functions I try in the configureChart extension function. Does anyone know how to do this ? When I make the entire object narrower in the designer it makes the text to small in the legend. Here is the code I have in the configureChart extention function for setting legend font, getting rid of the gradient, shadow and background grid: ```auto def configureChart(self,chart): from java.awt import Color from org.jfree.chart.renderer.category import StandardBarPainter from java.awt import Font darkColor = Color(43,43,43) lightColor = Color(213,213,213) plot = chart.getPlot() legend = chart.getLegend() chart.setBackgroundPaint(darkColor) plot.setBackgroundPaint(darkColor) plot.setDomainGridlinesVisible(0) #turn off background grid lines plot.setRangeGridlinesVisible(0) #turn off background grid lines plot.setOutlineVisible(0) #turn off background outline legend.setBackgroundPaint(darkColor) legend.setItemPaint(lightColor) # sets font color in legend d = Font("Dialog", Font.BOLD, 14) legend.setItemFont(d) #sets font in legend legend.setBorder(0, 0, 0, 0) #removes the legend border #removes the gradient rendering of bars and replaces with single colors renderer = plot.getRenderer() renderer.setBarPainter(StandardBarPainter()) renderer.setShadowVisible(0) #removes shadow on bars #these functions didn't work, error reported these methods didn't exist or they had no effect # renderer.setMaximumBarWidth(1) # renderer.setMaximumBarWidth(5) # renderer.setSeriesBarWidth(2,4) ``` ![Capture](https://us1.discourse-cdn.com/inductiveautomation/original/2X/4/4f06f2d451a054e3c2e61f336e1a719b0e62b5ac.png) ---

Looking into it, it looks like you need to provide a custom subclass of `StandardBarPainter` - you’ll notice [`StandardBarPainter`](http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/renderer/category/StandardBarPainter.html) calls `paintBar` with a [`BarRenderer`](http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/renderer/category/BarRenderer.html) - and that `BarRenderer` has a `getMaximumBarWidth()` method you could override. ---

I am still very new to using jython and external libraries. Can you provide a quick example ? Thanks ---

Actually, looking at it again, your commented out code should work fine - you're just missing one aspect - the `setMaximumBarWidth` function expects you to pass a _double_, which will be a percentage used: > Sets the maximum bar width, which is specified as a percentage of the available space for all bars Try passing `0.1` or `0.2` and see if you notice a difference in the final chart. ---

That worked thanks. I added the lineb below which resulted in the graph below. Now to figure out how to get rid of the little gray line at the top… ` renderer.setMaximumBarWidth(0.2) #value must be double and is a normalized percentage range 0 to 1` The complete code: ```auto def configureChart(self, chart): darkColor = Color(43,43,43) lightColor = Color(213,213,213) plot = chart.getPlot() legend = chart.getLegend() chart.setBackgroundPaint(darkColor) plot.setBackgroundPaint(darkColor) plot.setDomainGridlinesVisible(0) #turn off background grid lines plot.setRangeGridlinesVisible(0) #turn off background grid lines plot.setOutlineVisible(0) #turn off background outline legend.setBackgroundPaint(darkColor) legend.setItemPaint(lightColor) # sets font color in legend d = Font("Dialog", Font.BOLD, 14) legend.setItemFont(d) #sets font in legend legend.setBorder(0, 0, 0, 0) #removes the legend border from org.jfree.chart.renderer.category import BarRenderer from org.jfree.chart.renderer.category import StandardBarPainter #removes the gradient rendering of bars and replaces with single colors renderer = plot.getRenderer() print type(renderer) renderer.setBarPainter(StandardBarPainter()) renderer.setShadowVisible(0) renderer.setMaximumBarWidth(0.2) #value must be double and is a normalized percentage range 0 to 1 ``` ![Capture](https://us1.discourse-cdn.com/inductiveautomation/original/2X/b/bca4226a001bc6d73a17fcd513aa6626de3644fc.png)
