Feature request: add defined error bars

[Nipou]

The error in science is often different for each measure, so it would be really convenient to be able to define the range of data for the error bars.

So a new type : LXW_CHART_ERROR_BAR_TYPE_DEFINED
And an API void chart_series_set_error_bars_range(lxw_series_error_bars *error_bars, const char *sheetname, lxw_row_t row, lxw_col_t col);

The corresponding XML is simply:

<c:errBars>
<c:errBarType val="plus"/>
<c:errValType val="cust"/>
<c:plus>
<c:numRef>...</c:numRef>
</c:plus>
...

For clarity, where is set in the Excel interface. Is this a custom value?

For reference, here is the Python interface which supports custom values: Is that what you are looking for.

[Nipou]

Yes, see the attachment.

@Nipou Attachments are stripped from emails to GitHub. You will have to add it via the web interface. Or else just confirm that you are looking for support of custom values, like the Python API.

[Nipou]

Yes, it's custum values like the Python API.
