Hello,

All the charts in chartfx seem to have a small gap between the Y axis and the actual chart.

Am working on an area chart.

How can i take out the gap between the Y axis and the area chart so that the chart Sticks to Y axis.

Below is my code:

The set height and width also doesnot seem to work. Please help me out

 

ChartServer chart1 = new ChartServer(application, request, response);

 

List<MarketDTO> chartList = (List<MarketDTO>) request

.getAttribute("chart");chart1.getAxisY().setAutoScale(false);

Axis yaxis = chart1.getAxisY();

 

//chart1.getAxisX().setStyle(AxisStyle.FORCE_ZERO);FlashWriter w = new FlashWriter();

 

chart1.setGallery(Gallery.AREA);

 

chart1.setGrid(ChartGrid.HORZ | ChartGrid.VERT);

 

chart1.getSeries(0).setColor(java.awt.Color.red);

chart1.openData(COD.VALUES, 1, chartList.size());

//Find the max value to plot the Y axis and also get the chart points to plot the area graphlong maxValue = 0;long minValue = 0;

 

 

for (int i = 0; i < chartList.size(); i++) {

MarketDTO chartDTO = chartList.get(i);

 

 

if (request.getParameter("Nifty") != null) {

 

chart1.getAxisX().getTitle().setText("Time");

chart1.getAxisY().getTitle().setText(

"NSC Price List");chart1.setInsideColor(new java.awt.Color(66, 66, 66));

chart1.setBackColor(java.awt.Color.white);

chart1.setBorder(false);chart1.setImgSizeable(true);

chart1.setImgHeight(100);

chart1.setImgWidth(100);

chart1.setHeight(100);

chart1.setWidth(100);

chart1.setLeftGap(0);

chart1.setRightGap(0);

chart1.setBottomGap(0);

chart1.setTopGap(0);

Long chartValue = chartDTO.getClosePrice();

if (chartValue > maxValue)

maxValue = chartValue;

if (i == 0)

minValue = chartValue;

if (chartValue < minValue)

minValue = chartValue;

chart1.setValue(1, i, chartValue);

} else {

chart1.getAxisX().getTitle().setText(

"Time");chart1.getAxisY().getTitle().setText("BSC Price List");chart1.setInsideColor(new java.awt.Color(192, 192, 192));

chart1.setBackColor(java.awt.Color.magenta);

chart1.setBorder(false);

 

Long chartValue = chartDTO.getPrice();

 

if (chartValue > maxValue)

maxValue = chartValue;

if (i == 0)

minValue = chartValue;

if (chartValue < minValue)

minValue = chartValue;

chart1.setValue(1, i, chartValue);

}

}

 

// to round maxValue off to nearest max hundred int temp = 0;

temp = (

int) Math.round(maxValue);int mod = 0;

mod = temp % 100;

int maxresult = 0;if (mod == 0) {

maxresult = temp;

} else if (mod != 0) {

maxresult = temp - mod + 100;

}

//to round off minValue nearest min hundredint temp1 = 0;

temp1 = (

int) Math.round(minValue);int mod1 = 0;

mod1 = temp1 % 100;

int minresult = 0;if (mod1 == 0) {

minresult = temp1;

} else if (mod1 != 0) {

minresult = temp1 - mod1;

}

int setRange = 0;

setRange = (maxresult - minresult) / 4;

 

out.flush();

out.write(minresult);

 

yaxis.setMin(minresult);

yaxis.setMax(maxresult);

yaxis.setStep(setRange);

chart1.closeData(COD.VALUES);

 

// Assign all labels (this will help in tooltips)

java.util.Date dateTime = new java.util.Date();java.util.GregorianCalendar cal = new java.util.GregorianCalendar();

 

for(int j=0;j<chartList.size();j++)

{

int hr=cal.get(cal.HOUR);if(hr>=10 || hr<11){

chart1.getLegend().setItem(j, java.text.DateFormat.getTimeInstance(3).format(dateTime));

cal.setTime(dateTime);

cal.add(java.util.Calendar.MINUTE,8);

dateTime = cal.getTime();

 

// Set the X axis

chart1.getAxisX().setFirstLabel((short) 1);

//chart1.getAxisX().setMin(10);chart1.getAxisX().setStep((short) 2);

//chart1.getAxisX().setMinorStep((short) 4);chart1.getAxisX().setFont(new java.awt.Font("Verdana",java.awt.Font.ROMAN_BASELINE,9));

}

else if(hr>=11 || hr<1){

 

chart1.getLegend().setItem(j, java.text.DateFormat.getTimeInstance(3).format(dateTime));

cal.setTime(dateTime);

cal.add(java.util.Calendar.MINUTE,20);

dateTime = cal.getTime();

 

// Set the X axis

chart1.getAxisX().setFirstLabel((short) 1);

//chart1.getAxisX().setMin(10);chart1.getAxisX().setStep((short) 5);

//chart1.getAxisX().setMinorStep((short) 4);chart1.getAxisX().setFont(new java.awt.Font("Verdana",java.awt.Font.ROMAN_BASELINE,9));

}

else{

 

chart1.getLegend().setItem(j, java.text.DateFormat.getTimeInstance(3).format(dateTime));

cal.setTime(dateTime);

cal.add(java.util.Calendar.MINUTE,20);

dateTime = cal.getTime();

 

// Set the X axis

chart1.getAxisX().setFirstLabel((short) 1);

//chart1.getAxisX().setMin(10);chart1.getAxisX().setStep((short) 20);

//chart1.getAxisX().setMinorStep((short) 4);chart1.getAxisX().setFont(new java.awt.Font("Verdana",java.awt.Font.ROMAN_BASELINE,9));

 

}

}

 

 

chart1.setOutputWriter(w);

%>

<%=

chart1.getHtmlTag("450", "280","FLASH")%>

Thanks,

Deepthi
