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 am playing with candlestick graphs (example from here: https://apexcharts.com/javascript-chart-demos/candlestick-charts/basic/) everything work as expected.
However, I am struggling with adding my signal data for a visual representation of the graph.
I am unable to find a solution that works I was thinking I can somehow fine-tune a timeline - I tried chart.js/apexcharts and for now, I believe the closest will be with the second framework.
What I need is a bar chart that can be used in numeric ranges for the X and Y-axis as presented below. (the goal is to be able to add the green bar as presented)
Is there an easy win or an idea of how to approach this?
Is there something I am missing?
That is my current solution (line graphs with stopWin/stopLose and entry price).
Still suboptimal - but works and is easy to achieve.
After weeks of playing around with it - the solution stayed:
I got two instances of apexcharts one with candlestick and one with line graphs
they are in a single div with CSS playground and position absolute.
I am passing standardised min/max values and has to have the same amount of elements in them (line graphs are allowing You to add null values which allow using this solution.
The final version work is repeatable and looks good.
if you need some help in similar case - feel free to reach out ;)
I am using Data-Studio to generate charts. I am generating charts for compute instances based on their CPU usage,in time-series. When I generate a chart(a line chart) a few instances are represented as lines in the chart, which have specific CPU usage values, but the majority of instances get accumulated into a category called "others" and therefore I am unable to show the metrics for others and the chart is not very useful.
Is there any way this category others can be avoided in data studio? so that all the instances are represented by a line or a bar?
I am new to Data-Studio. Kindly help. Thanks
There are a couple of ways to display the chart Without the Others series:
1) Time Series Chart
If you are using Date in the X-Axis (Dimension) then I'd suggest a Time Series chart as it's designed for Dates, and automatically sorts by Date as well as allowing for Date Range comparison (it also don't display the Others series, and series can be displayed as a line or bar).
2) Line Chart
Regarding the initial question (Line Chart) - Tested this out in a number of different Reports and Data Sources to confirm, and it seems to do the trick:
Create a Time Series chart;
Change the Chart Type to a Line chart;
Sort by Date in Ascending order.
Google Data Studio Report and a GIF to elaborate:
Is it possible to extend the stock chart beyond the date of data being passed in?
For example, at 9:30am, I'd like to show the data that I have, but have the time range of the chart extend out to 4pm and show no data.
(Almost like a live view as the stock is being generated.)
I have tried adjusting the ranges, but it seems the chart just adapts to the data I have. Any help would be appreciated!
Currently, we can offer you the workaround: the additional null points will create the necessary empty space.
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 using Dynamic Data Display, for line chart (in WPF). I would like to interrupt the line, and display some "Error" label in that point (or on the X axis). Can somebody help me ?
Thank you.
You might use a DataPoint template selector for your datapoint in lineseries, when datapoint values are matching some errors criteria you can apply a different template to the datapoint and show an error label.
The way that I would approach this, is I would add a marker to your line graph every time this "error" occurred along your axes. If you wanted, you could make the tooltip for the marker say "error" or, even better, you could display some information about that error in the tooltip. You can use one of the markers already made in D3, or it's quite easy to create your own!
If you down load the source from Dynamic Data Display, there's many examples that have a similar requirement to yours that you could base your solution off of.
