Hello,

I am a new member here and just starting my work with this wonderful tool

I am having a curious problem when sending data to a TIMEPLOT.

There are 2 channels defined, 'Analog' and 'Temperatures'

My messages and data are happily making it to the chart for the channel 'Analog' but having no luck with the channel 'Temperatures'

Code for creation of series:

Code: Select all

 AnalogPlot.SetSeriesProperties("adc0", Plot::Magenta, Plot::Solid, 2, Plot::NoMarker);
              AnalogPlot.SetSeriesProperties("adc1", Plot::Green, Plot::Solid, 2, Plot::NoMarker);
              AnalogPlot.SetSeriesProperties("adc2", Plot::Blue, Plot::Solid, 2, Plot::NoMarker);
              AnalogPlot.SetSeriesProperties("adc3", Plot::Red, Plot::Solid, 2, Plot::NoMarker);
              AnalogPlot.Run(true);
              TemperaturePlot.SetSeriesProperties("tc0", Plot::Magenta, Plot::Solid, 2, Plot::NoMarker);
              TemperaturePlot.SetSeriesProperties("tc1", Plot::Green, Plot::Solid, 2, Plot::NoMarker);
              TemperaturePlot.SetSeriesProperties("tc2", Plot::Blue, Plot::Solid, 2, Plot::NoMarker);
              TemperaturePlot.SetSeriesProperties("tc3", Plot::Red, Plot::Solid, 2, Plot::NoMarker);
              TemperaturePlot.Run(true);

Code for updating these:

Code: Select all

 sDevice->printf("{TIMEPLOT:Analog|DATA|adc0|T|%lf}\r\n", analogResults[0].average);
                     sDevice->printf("{TIMEPLOT:Analog|DATA|adc1|T|%lf}\r\n", analogResults[1].average);
                     sDevice->printf("{TIMEPLOT:Analog|DATA|adc2|T|%lf}\r\n", analogResults[2].average);
                     sDevice->printf("{TIMEPLOT:Analog|DATA|adc3|T|%lf}\r\n", analogResults[3].average);

Code: Select all

for (itemp=0;itemp<8;itemp++){
                    if (peripheralStatus.tcExpPresent[itemp]==1) 
                        sDevice->printf("{TIMEPLOT:Temperatures|DATA|T|tc%d|%f}\r\n", itemp,thermocoupleMetrics[itemp].hotJunctionTemp);
                        //TemperaturePlot.SendFloatData("T"+String(itemp), thermocoupleMetrics[itemp].hotJunctionTemp,1);
                  }

The messages as they are arriving in Megunolink

{TIMEPLOT:Analog|DATA|adc0|T|3.469012}
{TIMEPLOT:Analog|DATA|adc1|T|3.471310}
{TIMEPLOT:Analog|DATA|adc2|T|3.471378}
{TIMEPLOT:Analog|DATA|adc3|T|3.470928}
{TIMEPLOT:Temperatures|DATA|T|tc0|27.125000}
{TIMEPLOT:Temperatures|DATA|T|tc1|26.875000}
{TIMEPLOT:Temperatures|DATA|T|tc2|26.000000}
{TIMEPLOT:Temperatures|DATA|T|tc3|0.000000}

The channels are defined in the TIMEPLOT Visualiser but only the Analog channel data is being added.

All of the series are added to the chart.

Any suggestions where to look?

This was just a screwup on my part, was sending things out of order with the Temperature channel.

Ie {TIMEPLOT:Temperatures|DATA|T|tc0|27.125000} should be {TIMEPLOT:Temperatures|DATA|tc0|T|27.125000}

Good catch!
