Relative values in the chart.
Hi
Is it possible to draw a graph in relative value?
Thank you.

Talking about recycling port = current speed divided by the maximum speed and multiply by 100%.
Global issues:
Ports can be at different speeds on the same device.
A local problem:
Suppose all the ports of the device with the same maximum rate, then it is likely somewhere in the derivation of the graph should be used to translation for "%".

+1
Graph 2 values (e.g. 200k and 40k) and also have the percentage between both in the same graph. It would be nice if the percentage value could be graphed relative to the highest data source and not flat lined.

That will be available with the COMPUTE data source. This is code available with 0.8.9, which currently is alpha. Please feel free to download from SVN and test. Don't hesitate to provide feedback in the "Unstable Development Versions" forum

Hello!
What is meant by "COMPUTE data source"?
Re: Relative values in the chart.
rrdcreate
COMPUTE
is for storing the result of a formula applied to other data sources in the RRD. This data source is not supplied a value on update, but rather its Primary Data Points (PDPs) are computed from the PDPs of the data sources according to the rpn-expression that defines the formula. Consolidation functions are then applied normally to the PDPs of the COMPUTE data source (that is the rpn-expression is only applied to generate PDPs). In database software, such data sets are referred to as "virtual" or "computed" columns.

The question of "rpn-expression".BSOD2600 wrote:COMPUTE

Where is will be available for drawing "rpn-expression"?
Re: Relative values in the chart.
Once again, the answer can be found in the rrdtool manual. I strongly suggest you take a read to answer these sorts of questions.
