spc toolkit

[cisgalicia]

Hi,

I'm going to repeat my message in English:

I try to develope a program in LabWindows/CVI. I want to do statistical process, so I installed the spc toolkit.

One of de process usues this function's group:

LGCreate LegendControl (panel, panel_graph, LG_POS_RIGHT_TOP, 1,1,
&xLegendCtrl)

SPCXBarAndR(data, SAMP_COUNT, SAMP_SIZE, NUL, NULL, 0, 3.00, NULL,
&xbarbar, NULL, Xbar, &limitsX, NULL, NULL, NULL)

SPCDrawChartWithZones (panel, panel_chart, xLegendCtrl, Xbar, SAMP_COUNT,
0,0, &limitsX, TRUE, 3)

My problem is that the last one give me an error: Graph or strip chart control does not exist or is invalid.

This message only appears if I create the graph control in the .uir like a normal graph, not like a "Classic-style" graph. In this case the program works correctly. The spc manual just indicates two restriccions for these kind of controls: they have to be VAL_RETAIN and VAL_AUTOSCALE.

So I can't understand what's the difference between both controls, why one of them works and the other doesn't.

Thanks everybody

The Graph validation code checks to see if the control style is of type CTRL_GRAPH. The issue is the newer graph is of type CTRL_GRAPH_LS.

The code for the SPC toolkit is included, so you could update this. In ..\spc\spc.c, under ValidGraphControl(), change the following

if (allowStripChart) {
        if ( ctrlStyle != CTRL_GRAPH  && ctrlStyle != CTRL_STRIP_CHART && ctrlStyle != CTRL_GRAPH_LS && ctrlStyle != CTRL_STRIP_CHART_LS)
            return FALSE;
    } else if (ctrlStyle != CTRL_GRAPH && ctrlStyle != CTRL_GRAPH_LS)
        return FALSE;

Then in SPCDrawChartWithZones()

ctrlStyle = ControlStyle(pan, graphCtrl);
    switch (ctrlStyle) {
        case CTRL_GRAPH: case CTRL_GRAPH_LS:
            return GraphDrawChartWithZones(pan,graphCtrl, legendCtrl, points,
                    pointCount, startIndex, xOffset, chartLimits, redrawLimits,
                    numZones);
        case  CTRL_STRIP_CHART: case CTRL_STRIP_CHART_LS:
            return StripDrawChartWithZones(pan, graphCtrl, legendCtrl, points,
                    pointCount, startIndex, chartLimits, numZones);
        default:
            return SPC_ERROR_NOT_GRAPH_OR_STRIP;


Under SPCGetChartPlotAttributes()

switch (ctrlStyle) {
        case CTRL_GRAPH:case CTRL_GRAPH_LS:
            return GraphGetChartPlotAttributes(pan, ctrl, whichPlot,
                    plotStyle, pointStyle, lineStyle, color);
        case CTRL_STRIP_CHART:case CTRL_STRIP_CHART_LS:
            return StripGetChartPlotAttributes(pan, ctrl, whichPlot,
                    plotStyle, pointStyle, lineStyle, color);
        default:
            return SPC_ERROR_NOT_GRAPH_OR_STRIP;
    }

This should fix it.
I hope this helps

Hi!

Thank you very much. Your explanation help me very much. I didn't know this detail. I will update my code and I hope it works!
