    Q-Client Scaling in graphs

    I have an archieve with light values.
    8-bit 0..100%/EIS6
    In Master data - Communication objects the Min value is 0 and max value is 100
    In Master data - Graphs I ticked Min/Max 1st Y-axis and used Min value 0 and Max value 100
    In QuadConfig I use the Graph Plugin.
    If I do not set "Specify limits manually" then in QC it shows 80 as max in the Y axis in 1 graph and 200 in another graph!

    When I do set "Specify limits manually" to Min 0 and Max 100 I get 200 as max for all graphs.
    I was expecting 100...

    How is this possible and corrected?
    Vielen dank!

    Nobody having the same issue?

      Was hoping that the 2.7 update would take care of it as I informed Gira about it quite a while ago.
      They corrected the arrows on the double Y-axis (601-CL_2_7-11 PlugIn 0-3 graph) but the other issue I reported, the scaling of graphs, was not touched.
      The temperature graph on QuadClient 1.4 uses the full Y-axis for a certain graph showing 16C - 20C while the same graph on the iPad shows a range of -5C - 20C
      This makes the graph almost useless.
      Same issue with the iPhone.
      The scaling issue with the light values is still there as well.
      I can hardly believe I'm the only one having these issues...

        No, you are not the only one. The way graphs are displayed within QC, iPad and iPhone differ. I have reported this to Gira and since then it's been very quiet. No response.

        As far as I know:
        • It's not possible to use more than 1 axis
        • Scaling of axes will lead to unexpected results
        • It's hard to tell how many data points you need, given a certain scale, to get a smooth line on all devices (QC, iPad, iPhone)

          This is not a problem of the Experte - software. This is a problem from the Gira-App. There should be a new version in the pipeline.

            I had some email contact with Gira as well until a few months ago when they decided not to respond to my questions/remarks anymore.

            Regarding scaling, I also have a graph with light brightness values.
            The communication data object is EIS6 (0..100%).
            Min value is obviously 0 en max value 100
            When using "Specify limits manually" in QuadConfig setting them to min 0 en max 100 I get a scale of 0..200 on Quadclient...

            I just tried a min of 0 and a max of 85 and now the scale on the iPad shows 0..50 and Quadclient still shows 0..200
            A max of 90 gives a same result.

            Looking further, it seems that the graph on the iPhone and iPad do not take into account the manual setting at all.
            When the graph is a flat line with a value of 0 it shows -5..5 on the Y-axis.
            In that case I do get a line on the iPad but no line at all on the iPhone!

            @Vento, would that be a problem of the iPad/iPhone app as well as the QC program?
            I'm using QC 1.4.1109.22

              Another issue which is still present is the determination of the min and max value in my temperature graph.
              It's as if it is only taking into account the values of 1 of the archieve data.
              In the screenshot below the blue line is not supposed to be flat...
              This software seems to be quite buggy.
              Even simple things are not working correctly.

                >6 months later and still having the same issues.
                The following 3 screenshots were taken at the same time from the QC, the iPad and the iPhone.
                Look at the weird scale!
