Hi all,
When we enable the rollover modifier and drag the chart, we can see the tooltip.
However, when I release the finger, the tooltip also disappears.
Is there a way to keep the tooltip showing when releasing the finger?
The problem we want to solve is user will use their finger to mark a critical point, then we will take a screenshot of the chart to generate a report.
Not sure if there is any good way to make the tooltip keeps showing to achieve this requirement?
Thanks

Hi,
I’ve been trying to customize the RolloverModifier tooltip content with a vertical chart but am at a loss to try to get the format I need. I’d like to take in all the series info and display them in a tooltip together with a small icon and the y-value next to this.
I was able to do this in the CursorModifier content but unable to do so in the RolloverModifier which is what I really want to use.
I’ve included a CodeSandbox link below showing the custom SVG template and output on the CursorModifier I’d like to use for the RolloverModifier. Is this type of output template possible?
Thanks in advance!

Hello,
When annotations and the rollover modifiers are displayed on the very left side of a chart they align with the center of the candlesticks on the chart. However, as they get displayed toward the right side of the chart they get more and more offset to the right side of the candlestick.
Can anyone point me in the right direction to figure out how to fix this issue seemingly with my xAxis?
See attached screenshots,

Hi, I’m looking for a way to programmatically dismiss a RolloverModifier from a chart. I’ve been tasked with creating a user experience that does two things: 1. when a user stops scrubbing on the chart, the rollover modifier should persist, and 2. when the user taps outside of the chart the rollover modifier should disappear.
I’ve accomplished the first part of the problem by implementing a subclass of SCIRolloverModifier and overriding the onEvent(args:)
function, but I cannot figure out how to dismiss the rollover modifier when the user taps outside the chart surface.
Is there a way to accomplish this?

Hello, I am using SciChartJS and have a new requirement from our users as follows that I need help with the implementation. Any pointers from anyone would be a great help.
**Requirements: **
- Assume that x-axis is Time and y-axis is prices.
- There are multiple series in the chart (e.g., Bid Price, Ask Price)
- Allow user to select a time on xAxis using
CTRL + CLICK
- When the user selects the time, show the rollover line and the tooltip for all series at the selected time
- This rollover line and tooltip should remain visible until the user selects a new time on the x-axis at which point the rollover tooltip should display the tooltip for the new point.
I started inheriting the RolloverModifier
but couldn’t find an appropriate method to show the tooltip.
So, I started implementing the above feature using CustomModifierBase2d
and adding a VerticalLineAnnotation
for the rollover line. But again, struggling with the tooltip.
If someone could help me out or give me pointers, that would be highly appreciated.
Best Regards,
Sachin Patel.

In our app we have a feature by which user can add indicators. These indicators can consist of 2 or a maximum of 4 lines.
We don’t want to render svg tooltips(which setted up by the default) with data for each line, instead of that we get point data and pass it to our app inner service that can render indicator legend.
To prevent default tooltips from being displayed we set for each renderable series of an indicator the following values.
rolloverModifierProps.width = 0; rolloverModifierProps.height = 0;
But of course tooltips are still rendered in the DOM and this leads to performance issues when we have 3 or more indicators of this type.
My question is the following
How we can render only circles svg for rollover modifier and completely dont render svg for tooltips in the DOM?
This is what the indicators look like

Hi,
the Tooltip from the rolloverModifier shows for the Open-Values the Label “Open”.
I would like to be able to change that. There might be serveral reasons for that. Maybe the shown data are not “openValues” or the word “open” needs to be translated into another language.
I managed to edit the title of a FastCandlestickRenderableSeries by setting a title and get it into the variable like this:
rolloverTitle = newtitle;
renderableSeries0.rolloverModifierProps.tooltipTitle = rolloverTitle;
unfortunately i did not find a way to set the name/label for the open-,low-,close-, or high-values of this Series.
Can someone give ma a hint how to do this?

Imagine I have a chart with a RolloverModifier, such that I see the point marker, and also a CursorModifier so I see the axis labels with the exact value I’m hovering.
This chart has the axis title hidden, and also the labels hidden, so I can really only see them trough the CursorModifier axis labels.
Since the axis title and labels are hidden, the axis labels spawn inside the chart, and the point marker from the RolloverModifier may be drawn on top of the labels.
I’d like to properly control drawing order here, so my axis labels get prioritised.
Is there a way to do so?

Hello,
I am having a problem where I want to display the Rollover Modifier only when I click on the selected graph.
For example:
https://demo.scichart.com/javascript-chart-rollovermodifier-tooltips
If I select the Second Lines Series, I want to see the rollover only for that particular graph and not the first one and the third one.
I have tried using charts id’s as a reference to show only one tooltip but it just enables it for all the graphs.
Any help would be kindly appreciated.

Hello, we have been working on our charts for more than a year now. The performance is really bad recently, it uses 100% of CPU when hovering on the chart, it seems to be an issue with the RolloverModifier, if we remove it; everything feels smother and the CPU usage is on normal levels. We tried rolling back to an old version of SciChart, but the problem persist. Any idea of what can be the issue?
