I am creating a point line graph with 4 horizontal lines. Across the bottom are years whose minimum is 1 and whose maximum value varies from 5 to 12. I am graphing vertically dollar amounts whose magnitude varies. I have successully figured out everything EXCEPT adding 4 rows of annotations across the graph echoing the exact yvalue in the same color as the line. When I use a series paint listener and try series painted calc x pos method returns the values I'm looking for but the annotations do not show up on my graph. If I use series painting or myChart.refreshControl (saw in an example) without a listener they come back zero and all of my annotations print way to the left and on top of each other.
I am trying to mimic what was done in a VB application by calculating the top and left positions of teh annotations
Here is the code at the bottom of my routine (sorry for the formatting)
myChart.refreshControl();
// myChart.getSeries(0).addSeriesPaintListener( new SeriesPaintAdapter() {
// public void seriesPainted(ChartDrawEvent e) { int seriesCount = myChart.getSeriesCount(); int toolsmax = 0;
for (int iseries = 0; iseries < seriesCount;iseries++) {
toolsmax += myChart.getSeries(iseries).getCount(); }
Annotation[] tools = new Annotation[toolsmax];
int itool = 0;
for (int iseries = 0; iseries < seriesCount;iseries++) {
int count = myChart.getSeries(iseries).getCount();
ValueList values = myChart.getSeries(iseries).getYValues();
for (int i = 0; i < count;i++) { int xval = myChart.getSeries(iseries).calcXPos(i);
double value = values.getValue(i);
tools[itool]= new Annotation(myChart.getChart());
myChart.getChart().getTools().add(tools[itool]);
tools[itool].setText(Format.formatNumber(value,"#,##0"));
tools[itool].getShape().setTransparent(true);
tools[itool].getShape().setCustomPosition(true);
tools[itool].getShape().getFont().setSize(7);
tools[itool].getShape().getFont().setColor(lineColor[iseries]);
int leftMargin = xval; if (i == 0) {
leftMargin -= 6;} else if (count == 12) { leftMargin -= (i*4); }
else if (count == 10) {
leftMargin -= (i*5); }
else if (count == 9) {
leftMargin -= (i*6); }
else if (count == 8) {
leftMargin -= i*7); }
else if (count == 7){
leftMargin -= (i*8); }
else if (count == 6){
leftMargin -= (i*9); }
else if (count == 5){
leftMargin -= (i*10); }
tools[itool].setLeft(leftMargin);
tools[itool].setTop(lineOffset[iseries]);
itool+=1;
}}
// }
// });
try
{
myChart.getExport().getImage().getJPEG().save(jpgFileName);
}

Hi cathy,
You should use the chart paint listener for having valid positions and setting annotations custom position there. You'll find more information about that at Tutorial 10 - Custom drawing on the Chart Panel included with TeeChart's installation.
Another custom drawing example can be found here.
If this doesn't help please send us a code snippet we can run "as-is" to reproduce the problem here.
Thanks in advance.
