Names in Charts

What do you mean by minimize the space?  Are you hoping to separate each word of the y-axis labels with a newline rather than a space? 

The requirement is if you see in the above chart "warranty" taking less space but because of" new product development "the entire graph moving right side .I want the new product development name should come in 3 lines so that it will also take same space as warranty

Sorry it's not possible. If you go through my below code I reserved only one third of space in Columns layout for bar chart . .So it adjusted itself (Titles and Bars) to utilize the space. The result is New Product development came as two lines. If i didn't have that restriction it would look like your screenshot

{
  a!columnsLayout(
    columns: {
      a!columnLayout(
        contents: 
    a!barChartField(
    label: "Bar Chart",
    labelPosition: "ABOVE",
    categories: {"Competitor analysis", "Compliance Check", "Field Quality", "New Product Development","Warranty"},
    series: {
      a!chartSeries(label: "Chart Series", data: {1, 2, 3,2,3})
    },
    stacking: "NONE",
    showLegend: true,
    showTooltips: true,
    allowImageDownload: true,
    colorScheme: "RAINFOREST",
    height: "MEDIUM",
    xAxisStyle: "STANDARD",
    yAxisStyle: "STANDARD"
  ),
  width: "3X"
  ),
    a!columnLayout(
      width: "3X"
    ),
    a!columnLayout(
      width: "7X"
    )}
  )
}

Ok thankyou venkat
