QT CHARVIEW EXAMPLE SERIESAgain, this is the same pie chart from the previous example: QPie Series series Pie new. For the x-axis we use the QBarCategoryAxis and for the y-axis we use QValuesAxis. View (chart Bar) chart View Bar->setRender Hint (QPainter. The example uses Qt Quick Controls to provide controls for the pitch, volume, and rate of the speech. The Quick Speech example demonstrates how the TextToSpeech type can be used in a Qt Quick application to read out text, and to control the speech. With custom axes we set the range of both series to follow the same axis. The Quick Speech example reads out user-provided text. If we don't create custom axes, then each series will get scaled to use the maximum area of the chart (like in single series case) and the result will be incorrect. To make the chart show the series properly, we have to create custom axes for the series. To run the example from Qt Creator, open the Welcome mode and select the example from Examples. This application shows you how to customize different visual properties of a ChartView and series. QChart *chart = new QChart() Ĭhart - >setTitle( "Line and barchart example") The example shows how to create your own custom zooming effect. Here we create the chart and add both series to it. QLineSeries *lineseries = new QLineSeries() To make the data match with the barchart, we use the index as an x-value for our line series, so that first point is at (0,value) second at (1,value) and so on. Then we create a line series and add data to it. For more information, visit Building and Running an Example. To run the example from Qt Creator, open the Welcome mode and select the example from Examples. In the example we combine a linechart with a barchart and use the category axis as a common axis for both. ![]()
