How to display Tornado bar chart variable and it's min and max value using QWT

[RBSahu]

Hi All,

I have created Tornado plot using QwtPlotMultiBarChart Class.

I want to display Variable and it's min and max value on tornado bar chart.

code snippet given below.

To do color tornado bar chart used below code.

// set red color on left side of tornado bar 
	QwtColumnSymbol *symbol = new QwtColumnSymbol(QwtColumnSymbol::Box);
	symbol->setPalette(QPalette(Qt::red));
	tornadoBarChart->setSymbol(0, symbol);	
 
	// set blue color on right side of tornado bar 
	QwtColumnSymbol *symbol2 = new QwtColumnSymbol(QwtColumnSymbol::Box);
	symbol2->setPalette(QPalette(Qt::blue));
	tornadoBarChart->setSymbol(1, symbol2);

// set red color on left side of tornado bar 
	QwtColumnSymbol *symbol = new QwtColumnSymbol(QwtColumnSymbol::Box);
	symbol->setPalette(QPalette(Qt::red));
	tornadoBarChart->setSymbol(0, symbol);	

	// set blue color on right side of tornado bar 
	QwtColumnSymbol *symbol2 = new QwtColumnSymbol(QwtColumnSymbol::Box);
	symbol2->setPalette(QPalette(Qt::blue));
	tornadoBarChart->setSymbol(1, symbol2);

To copy to clipboard, switch view to plain text mode 

QVector<QVector<qreal>> minMaxVector;
    sortMinMaxDiff(minMaxMap, minMaxVector);	
    TornadoWidget = new TornadoPlot(optimumMudweightbaseValue, minMaxVector, units);	
    TornadoWidget ->setWindowTitle("Tornado Plot");

QVector<QVector<qreal>> minMaxVector;
    sortMinMaxDiff(minMaxMap, minMaxVector);	
    TornadoWidget = new TornadoPlot(optimumMudweightbaseValue, minMaxVector, units);	
    TornadoWidget ->setWindowTitle("Tornado Plot");

To copy to clipboard, switch view to plain text mode 

thank you for any kind for help.

Hi Uwe,

I have created tornado plot.
Now my next requirement is to print the value of tornado bar.
For reference I am attaching screen shot where tornado bar value is printed.
Similarly I want to print tornado bar value using qwt function.
Which function of class can be used to print tornado bar value.



thank you

Yes I want to print bar value and text.

Overload one of the drawXY methods and use QPainter::drawText or QwtText::draw.

HTH,
