I have a chart which has a maxValue for y-axis hardcoded to 100. Is there a way I can make this dynamic? Because my counts normally are ones and tens but can go up to thousands or even ten thousands. If thats the case then the column wont even render and chart will be blank since maxValue is only 100.
Thanks
I inspected my chart object in debugger and saw I have access to its axes and digged down further and got access to maximum config.
this.getChart().axes.items[0].maximum = maxValHere;

I am trying to add one box and one line on x-axis. Please look at below bar chart.
I tried using stripline but I cannot set height for stripline. It goes till 100.
Is there any way I can do this?
Unfortunately, SSRS doesn't provide the functionality you're looking for. A stripline is the closest you can get to that, but like you said, you can't control its height. The only way you could simulate this behavior would be to use a Background Image for your stripline, but that may be more work than it's worth. It would require a lot of manual adjustment to get the image to line up on the chart.
I would add a series to the chart using the Stock chart (under Range). In the Series Properties I would set the High value to the height desired for your line (~52 in your example). Ideally this would come from a dataset value.
Set the Low, Open and Close values to 0.
Try two Stripe Lines. First, create the strip line which represents the vertical value you're after. In my case, I made one that was 50% of the graph height off of the Y-Axis.
Chart Properties:
Height of StripeLine:
Once the stripe line is the correct height for the chart, create a 'mask' stripe line along the X-axis that will cover the portion of the Y-axis line you want hidden.
Chart Propterites:
Width of Stripe Mask:
Using these methods, and some really clever expression writing, you should be able to make the line exactly as high, and as wide as you desire.
I'm working on getting familiar with Sencha charts. I'd like to know if there is any way that I can extend a column outside of the view port. For example I have data for which I have the min, first quartile, third quartile, and max for and I make a stacked chart out of these. However the max contains several outliers that probably won't be relevant to the user. What I want to do is end the view after the third quartile somewhere. Is there a simple and easy way to accomplish this?
You would have to work out the algorithm to get the percentage of records that go beyond your third quartile. That shouldn't be too hard.
Then create a function that set's the chart's width to a size which is equal to:
[viewport width] * (1 + [the percentage])
You can use the chart's setWidth method for this.
You can call this function in the chart's beforerefresh event (it should fire after the chart store data is loaded but before it is rendered on the chart) and also in the viewport's resize event.
I am trying to load dataset during initialization of the JFreeChart. But every time I tried to create a dataset with higher "number of item per series", the more data (all data) displayed visible in the chart (the bigger the dataset, the smaller the graph). But actually what I wanted is to have the fixed range of dataset values displayed on the chart while the rest is still hidden. Just the same way the data would normally be displayed in the actual trading platform, let's say Metatrader (MT4). First time when I open the chart I can see the screen filled with the only visible dataset of the chart and if I left-scroll the chart I will be able to see the old/history dataset as well. Does anyone have idea how to achieve this using JFreechart?
Really appreciate for any help or any thing/articles I can refer. Thanks so much!
You can use setRange() on either the domain or range axis, as shown in this fragment. If you've already tried this, it may help to edit your question to include an sscce and/or image that exhibits any problems you encountered.
I'm trying to create a sparkbar (very similar to a sparkline) that can have a range of data, and needs to be displayed next to other sparkbars with the same type of data for the same time frame. The majority of the values are within +/- 10 units. However, sometimes outliers are much greater. This means that if we keep each plot consistent by scaling to the max values, most of the charts are flat with just the odd ones being clear.
Our solution is to display the majority scaled to +/- 10 and the rest have their axis expanded to the full range of values, with some indicator that they are "special". For example:
Normal vs Special
However, you can see that the special one isn't that clear.
Does anyone have any suggestion on how to indicate better? One suggestion is to add a grep bar behind at +/- 10 similar to this:
Any thoughts?
I have a silverlight chart with an Area Series.
my data source returns many points representing time of day to be displayed in the chart's X-axis.
since the X-axis has many values, the values appear scrambled as each value is stuck beside the next value.
is there a method to avoid displaying all the values in the X-axis and display intervals instead ?
thanks
The DateTimeAxis has Interval and IntervalType properties that allow you to set the interval the you prefer.
