When the data is up to 50, my page is displayed on the x-axis of days one after another. But when the data becomes more than 60, due to responsive design, days start to be skipped and shown after 1.
I figured out that ChartJS still renders as specified in the settings. But due to the scale of the page, the graph adapts and skips days. Can this be fixed?
At 80% page scale, the days go one after the other. But at 100%, the days start to skip and show through 1.

I count in bins the amount of different events and I indicate the central bin as bin of interest using X-Axis constant line.
Now I want to show on which ID a bin starts and ends. But then my X-axis line went away.
I guess that is caused because the report switches from continous to categorial type.
Is there a possibility that report keeps continous or how can I add such x-axis spike line?
I have also realised that the continous types shows all columns without scrollbar and categorial adds a scrollbar. Is there a possibiliry that categorial type also shows all columns without scrollbar.
I have a problem in flutter in listview.builder where it only renders the shown items, not all of them (even if they were not shown), and when I scroll down or up it renders the not shown items and re-renders the already rendered items.
It's not actually a problem, It's good for the phone memory to only render the shown items, but for me, it's a problem, because it's difficult for me to do some manipulations on the items.
the manipulations are like getting data from every item like the price of the item if it was higher than $100 and then printing the total amount of them on the bottom of the screen.
I can't do this one, because it doesn't show all of the items to get the data from them, and when I scroll down, it gets the data from the not shown items, but when I scroll back up, it gets the data from the already shown items again !
for Example, if the shown items have this data = 300, and the not shown items have this data = 800, at first it will get 300, and when I scroll down, it will get 1100, but when I get back up, it will get 1400
I really want to fix this problem, it's holding me back from finishing my project.
Thank you so much for your time.
I solved the problem by only putting Listview.builder in SingleChildScrollView, and that solved all the problems.
I have a line chart with two datasets. Initially the Y Axis is 0-100. The first line is roughly a straight line around a value of say 70, the second line is all below say 30. If I zoom the chart vertically by forcing the Y Axis min to 65 and max 75 (ie I want to exam the first line expanded vertically) then when I hover over a data point, the tooltip is missing. Actually I figure it is off the chart (so to speak :-) ).
The tooltip seems to be automatically positioned vertically between the lowest and highest data points, even if one of those data points is way below the chart.
My question: is this a bug or is there a way I can tell chart.js to ignore data points that are off chart when determining tooltip vertical position?
I'd even be happy if the tooltip was always at a fixed vertical position, ie across the top of the chart or centred vertically on the chart.
Using chart.js V2.7.1
Tooltips have two positioning modes, as per the documentation:
Possible modes are:
'average'
'nearest'
'average' mode will place the tooltip at the average position of the items displayed in the tooltip. 'nearest' will place the tooltip at the position of the element closest to the event position.
You can see both modes in operation at the relevant samples page.
average is the default mode. From your description, switching to nearest should resolve your issue.
I have an Amcharts in a tab but when it is created on page load, it is compressed with an incorrect (too small and sometimes to 0px) height. When I switch tab and come back to the chart tab, then I can clearly see that it is resized and looks perfectly after some visible height changes.
I have seen a bunch of similar topics, but they all complain about the chart having a small size only when arriving on a tab and not on page load directly.
I have tried to call invalidateSize(), validateNow(), etc. after the chart is built on page load (even with a timeout) but it doesn't do the job.
Is it because of the container that wouldn't give enough info to Amcharts to process the correct size? How come Amcharts is able to recalculate the size of the charts when changing the tab and back to the chart one?
Would you please have any hints for me? Thank you very much
I use Bootstrap tabs system.
I have finally solved it by setting a fixed height
.amcharts-chart-div{
height: 436px !important;
}
My time-series-style Google Chart (google.visualization.DataTable) isn't showing times in the x-axis; only the dates.
How do I get it to show time increments on the X-axis? I understand how to update the formatter to show times, but there's no x-axis values in the first place, as seen in this screenshot:
