Create a chart based on data from another

[datanibbler]

Hi,

is it possible to create a chart solely based on data taken from another chart (generated only on the UI)?

<=> The information I need is created using some set_analysis and data from several underlying tables.

        Generating it directly in the underlying tables would not be an easy task.

Thanks a lot!

You are use the same expression here in new chart then apply your new expression with analysis because the same expression give same out put to you on new chart.

You can find all of those same expressions in settings -> chart overview if you want to use them again

No, a chart cannot use data from another chart. Charts don't 'have' data, but can only display data. But you can probably create expressions to get the result you're looking for. Possibly using the aggr function to create virtual tables that can be manipulated further.

Hi Gysbert,

thanks for the answer!

I thought so. But I guess we'll find a way. After all, what we need is just the data we have displayed in one chart - only we need a different kind of chart with another dimension - so I guess we can just copy it and make the appropriate changes to get what we want.

Btw.: I think I saw once that it is possible, in the "flow" of a chart, to make the expressions "further down the line" refer to those before just by name?

In some instances, that might actually make understanding quotas and such easier ...

Thanks a lot!

You can give expressions in a chart a name. In straight tables and pivot tables that's also the label used in the header. You can use that name to refer to that expression in other expressions. It's also possible to store expressions in variables and use and reuse those variables in place of the fully expanded expression. That way you can build up complex expressions from simpler components. And it's also possible to pass parameters to variables. See this post for an example: Re: Multiple definitions for one Variable.
