Root cause:

In pdfgen_chart.py we have a hard-coded value (600) for the width of chart and that is why labels are hidden in pdf.

class Chart(SvgBasedViz):
    def init(self, data, fields, props, locale, runningAsScript=False):
        SvgBasedViz.init(self, data, fields, props, width=600, height=350, genSvgScriptName="gensvg.js", runningAsScript=runningAsScript, locale=locale)

This truncates the labels if the chart width is exceeded.

Workarounds:

Go to the dashboard:

a. Export> Print> Destination> Save as PDF
Or
Use the browsers 'Print' as 'Save as PDF' option.

b. You can increase the width value from 600 to a value that suits your requirement. I suggest you to try 1000.

The pdfgen_chart.py script is in the following path "C:\Program Files\Splunk\Python-2.7\Lib\site-packages\splunk\ pdfgen_chart.py

Post changes restart the search head(This is where you need to change this value).

Note:
1. Increasing this value will change the visualizations of other Pdf's.
2. You need to take backup of this script in case if you are going to upgrade the splunk.
Reason: While up gradation this script will be replaced.
3. You can do the modifications at your own risk.

excause me, is it possible to change the hard-coded value (600) by input parameter, but not increase the width value in the pdfgen_chart.py?
