1. Setting domain axis range for Sliding datasets jfree.orgHi, AFAIK the sliding dataset is implemented such that there are a number of points/values shown in the graph window and allows to slide through the entire dataset by specifying which point must be shown first. I am using an implementation of SidingXYDataset found here: http://sourceforge.net/tracker/index.php?func=detail&aid=2439953&group_id=15494&atid=315494 which is implemented as SLidingCategoryDataset, meaning I can only specify the number of points shown ... |
2. 2nd CategoryAxis doesn't show categories of 2nd dataset jfree.orgI created a CategoryPlot containing two CategoryAxis (domain) and two NumberAxis (range). Two datasets were added into the plot and mapping to different domain axis / value axis / rederer. The value axis and renderer all works fine except that the Second category axis wrongly shows the category of first dataset not the second one. I traced into the CategoryAxis, found ... |
3. MultiCategory dataset: X-axis labels overlapping. How 2 stop jfree.orgI am using a multiCategoryDataset to draw various graphs such as line, bar and pie charts. On the line charts if there are a lot of entries on the X axis, the labels overwrite each other into a black blur. How do I tell JFreeChart to skip labels if necessary to ensure that the labels are visible? As it turns out, ... |
4. Non-linear axis; Capture sparse occurences in dense dataset jfree.orgI want to know if JFree Chart can handle a non-linear (non-uniform) temporal axis. My data is dense and the user will likely be interested in entities that appear for a very short duration and do not return later in the dataset. I want to "magnify" or "amplify" or in some other way call attention to those areas. As an example, ... |

Actually Im setting the dates as String to be the Categories. The problem is the data isn't comming sorted. Is there a way to sort the categories or should I use a different Dataset to plot sorted Date data? Thanks! |
8. Mapping Dataset to domain Axis jfree.orgHi Guys, I'm currently facing the problem that I've got 3 Renderers with 3 different datasets and 2 Rangeaxis. When all of the datasets have the same categories, everything is working fine. But sometimes, for one dataset, some categories are missing (because no data) Is it possible to "map" the datasets to the domainaxis, so that missing categories are skipped? At ... |

11. Chart with axis having the points based on dataset jfree.orgI want to generate the Line Chart having the X- axis as date and Y-axis as decimal values. Currently, chart auto scales the plot on X-axis and Y-axis based on data in dataset. My requirement is to show only plot on X-axis and Y-axis for which data is present in dataset. For example, my data set is something like date(X-axis) value ... |
