How to show bars in JFreeChart which has 0 for the Y Axis?



I am having a clustered bar chart generated from JFreeChart. I have observed that the bars will only appear once the Y Axis value is greater than 0. I need to show the bars which has Y Axis value 0 also.



I have searched many times in google, but I couldn't find a solution for this.



Appreciate if you can help me to do this.



enter image description here



My Code:


public static void generateBarChart() throws IOException, ParseException {

final DefaultCategoryDataset dataset = new DefaultCategoryDataset( );

dataset.addValue( 0 , "Failed" , "Spec 1" );
dataset.addValue( 3 , "Passed" , "Spec 1" );
dataset.addValue( 0 , "Skipped" , "Spec 1" );

dataset.addValue( 2 , "Failed" , "Spec 2" );
dataset.addValue( 0 , "Passed" , "Spec 2" );
dataset.addValue( 1 , "Skipped" , "Spec 2" );

JFreeChart barChart = ChartFactory.createBarChart(
"Bar Chart",
"Count", "Spec Name",
dataset,PlotOrientation.HORIZONTAL,
true, true, false);

CategoryPlot plot = barChart.getCategoryPlot();
plot.getRangeAxis().setStandardTickUnits(NumberAxis.createIntegerTickUnits());

plot.getRenderer().setSeriesPaint(0, Color.RED);
plot.getRenderer().setSeriesPaint(1, Color.GREEN);
plot.getRenderer().setSeriesPaint(2, Color.BLUE);

ChartPanel chartPanel = new ChartPanel(barChart, false);

chartPanel.setBackground( Color.WHITE );
barChart.getPlot().setBackgroundPaint( Color.GRAY );
barChart.setBorderVisible(true);
barChart.setBorderPaint(Color.BLACK);
((AbstractRenderer) plot.getRenderer()).setBaseLegendShape(new Rectangle(20,20));
LegendTitle legend = barChart.getLegend();
Font labelFont = new Font("SansSerif", Font.TYPE1_FONT, 14);
legend.setItemFont(labelFont);

Font categoryAxisFont = new Font("SansSerif", Font.TYPE1_FONT, 14);
CategoryAxis categoryAxis = plot.getDomainAxis();
categoryAxis.setTickLabelFont(categoryAxisFont);
categoryAxis.setLabelFont(new Font("Dialog", Font.TRUETYPE_FONT, 14));

Font rangeAxisFont = new Font("SansSerif", Font.TYPE1_FONT, 16);
ValueAxis rangeAxis = plot.getRangeAxis();
rangeAxis.setTickLabelFont(rangeAxisFont);
rangeAxis.setLabelFont(new Font("Dialog", Font.TRUETYPE_FONT, 14));

// Value on the bars
plot.getRenderer().setBaseItemLabelGenerator(new StandardCategoryItemLabelGenerator());
plot.getRenderer().setBaseItemLabelsVisible(true);
plot.getRenderer().setItemLabelFont(new Font("Dialog",Font.BOLD,12));
ItemLabelPosition position = new ItemLabelPosition(ItemLabelAnchor.INSIDE12,
TextAnchor.TOP_CENTER);
plot.getRenderer().setBasePositiveItemLabelPosition(position);

int width = 600;
int height = 800;

// Save it, if the pi-chart directory is not there create it
File directory = new File(barChartDir);
if (! directory.exists()){
directory.mkdirs();
}

File BarChart = new File( getSavedBarChartImagePath() );
ChartUtilities.saveChartAsPNG( BarChart , barChart , width , height );
}



Thank You.

Clash Royale CLAN TAG #URR8PPP Arduino Mega cannot recieve any sketches, stk500_recv() programmer is not responding Yesterday we were trying to update the firmware of our 3D-printer a Tevo Tarantula i3 The printer was running Marlin 3D Printer Firmware. We installed a new module a TL-Touch Sensor, a chinese copy of the Bl-Touch an auto bedleveling touch sensor for a 3D printer. After re-configurating a new version of the firmware for our setup in the Arduino IDE we went on with uploading the sketch to the Arduino Mega that was controling our 3D printer. Before we started uploading we made sure the right COM-port was selected in the Arduino IDE and that also the right type of Arduino was selected. The Arduino Mega 2260. Then we started with compiling the firmware and then uploading it to the Mega, Somewhere in between that moment the IDE freezed and crashed. As a response we removed the USB cable that was connected from the PC uploading the firmware onto the Arduino Mega, (This was a st...

Clash Royale CLAN TAG #URR8PPP C++ virtual function: Base class function is called instead of derived I have following code snippet: using namespace std; class base { public: virtual void print(char a){ std::cout<<" Base "<<std::endl;} }; class derived :public base { public: void print(floata) {std::cout<<" Derived "<<std::endl;} }; int main() { base* d = new derived; d->print(1.5); return 0; } Output is "base" Why output is coming from base function and not from derived one By clicking "Post Your Answer", you acknowledge that you have read our updated terms of service, privacy policy and cookie policy, and that your continued use of the website is subject to these policies.
