Hello everyone, We are seeing an issue with charts when time format is set to Japanese. Prices are being plotted as expected when time format is set to anything else i.e. EDT, BST etc. Can someone please let me know if there are any known issues with JFreeChart and Japanese time format? There is no ...

Can any of you please specify if there is a way to make sure that bar renderer plots the full bar when weekends are excluded?

Hello,

We would like to purchase a contract for exclusive support of JFreeChart API in order to resolve some of the outstanding issues. Can any of you please guide me through the steps as to how to get this done?

Any help is much appreciated.

Thanks,

In addition, it must be worth noting down is that candlesticks are being plotted as expected (2 halves) even though weekends are excluded. CandlestickRenderer provided by the framework is being utilized for candlestick charts.

When weekends are excluded using monday through friday segmented time line for a combined domain xy plot, the width of the volume bars are reduced to half and only right half of the bars are plotted. This is because mid night time is the reference time used. Since weekends are excluded, bar plot whi...

Does it mean that SegmentedTimeline implementation will not be part of jfreechart 2.x?

I am using a segmented timeline created by SegmentedTimeline.newMondayThroughFridayTimeline() for my date axis. This is hiding Saturday/Sunday from date axis as expected. However, whenever there is data for saturday/sunday time frame, the data is being appended to Monday's data which is incorrect. F...

Can someone from jfree support please respond to this question?

All, I would like to quickly check if JFreeChart API supports a percentage axis in order to show the percentage gain or loss over a period of time. For example, when comparing the price movements of IBM and SPY in one chart, would like to look at the gain/loss percentage on the range axis. We have b...

This whole question actually boils down to "Should the charts be showing date tick label for Saturdays when they are excluded using SegmentedTimeLine?" We would not have had this issue if there is no vertical grid line shown for Saturday. Because it is displayed and there is another vertical grid li...

Date is merged incorrectly when using SegmentedTimeline.newMondayThroughFridayTimeline() on my charts. For Example: I have the historical data for my one-week-history-chart since 22nd June. This chart excludes the week ends from plotting as there will not be any trading activity. I have the data for...

Hi, I am currently working on copying a JFreeChart to the System Clipboard so that it can be emailed just by pasting the cpoied chart. I did use the export functionality available with JFreeChart to save the charts as JPEG or PNG images. However, this time the users do not want the charts to be save...

Hi, I have a Chart, which displays the data Price vs Time of a selected stock, with several overlays added to it. Let us assume that the chart displays price movement in a day and it has an overlay such as Exponential Moving Average. The requirement is to display EMA value as the user mouse hovers o...

Hi, At last, we decided to add a menu in place of adding combo boxes to the toolbar, to avoid this kind of rendering problems. Menu is working fine and does not have any issues so far. I am currently working on developing a charting framework for a trading product (Mostly the domain axis is Time and...
