JasperReports (iReport) Chart Define X Axis Tickcount - jasper-reports

Find a screen from my report attached.
It is an AreaChart with a category dataset in a multiple axis chart.
The Y Axis is well formed.
The X Axis is not.
The X Axis is based on a Timestamp field.
Can I configure the TickCount in iReport?
The X Axis has to be exploded like Y axis.
I´m working with actual iReport and don´t have permission to use Java.
thx and Best regards
Christian

Sometimes, un-checking and re-checking the tick-mark buttons in the chart's properties window will work..

Bubble charts Vaadin: how can i set the axes origin on coordinates 0,0

Now vaadin set X axis on min vertical value(bottom) and Y axis on min horizontal value (left), but i will like set axes on middle
I'm afraid that axis are always in left and bottom of the plot area.
One thing you can do is set the min at negative, or leave it automatic, and add a plotline with value 0 for both axes. That way you can visualize the chart's quadrants.
If you're using java API you can use addPlotLine method in xAxis or yAxis classes. You can check the java tab in the boxplot demo

Second Y-axis labelling in cognos chart

I have a simple line graph that shows daily pricing for 3 months. I need another Y-axis on the right to be label as the same scale on the left. How can it be done?
I'm now using secondary axis to do this which will have 2 lines overlapping together which is ok as it does not affect my graph. However it shows an extra element for that secondary axis in the legend. How can it be removed?
Please help. Thank you.
You can install the customizer and go to chart properties in order to see if you can use second Y axis labelling or not.

jaspersoft jfreechart range or y axis is derived incorrectly

I am using jasper reports with charting. The chart generally works with a wide variety of values.
In one case the values are either 1.011 or 1.01 for the range or Y axis. That is, the user tries to generate a chart and some of the values are 1.011 and some are 1.01.
The challenge is, when generating a chart with these values, the chart is scaled incorrectly on the range or Y axis. The labels range from 1.000 to 1.010 with increments of .001. As the top of the chart is 1.010, the values 1.011 fall off the top of the chart and don't appear on the chart.
Can anybody explain how the range or Y axis is derived beyond stating that the axis is derived from the data. And why, in this case, is the axis derived
incorrectly?
Is there a way to configure the chart to display the range or Y axis more correctly?
I edit a jrxml file. I do not use iReports or java api.
Thanks for all of your assistance and good ideas

Multiple YAxis with different tick size

Just want to find out if anyone have encountered this problem before.
Basically I am currently using Flot version 0.8. I am trying to plot a chart with multiple yaxis against datetime in xaxis.
The Left yaxis are for values which normally range between 10-80 whereas right yaxis are for values range between 100-500.
Is that even possible to have them plotted with the same tick size (E.g., 20) and the dimension of the chart is fixed.
At the moment, FLOT will automatically apply different tick size on left and right yaxis.
What do you guys think?
Use the tickSize option to set the same interval on both axes. See the customizing the axes section of the docs for more info.
