The attached xml file is a save of a C1Chart.
It loads fine however when you look at the data for the series the hole values are not appearing as “(hole)”. Changing the axis to auto scale results in the chart showing the hole value as a chart value.
Is there a work round to fix this? If needs be i can pre-process the file.

Hi Steven,
The xml file you’ve shared does not contains any information regarding data holes. Hence when it loads the hole values seems to be missing. To resolve this you can set any specific value as hole using the ChartData.Hole property as shown below:
chart.ChartGroups[0].ChartData.Hole = -1000
You can also use double.NaN for the same purpose. C1Chart treats double.NaN in data as a hole. Please refer the attachment for sample and xml file as an example.
Hope it helps.
Regards,
Basant

Thanks for the reply. Just a for interest why is the default Hole value (3.40282346638529E+38) which is used in the file not being recognised.

Any chances that you are loading and saving the file on different systems? At my end, float.MaxValue is shown as 3.4028234663852886E+38 and hence while loading your xml the holes are not shown. Whereas, if I save a new xml the holes are saved as 3.4028234663852886E+38 only and on loading the same the holes are shown correctly. So probably it is the difference of float.MaxValue on different systems that the holes are not getting recognized.
Thank you.
