Hi,

Do you have an active case open for that issue ? I was not able to find one. If you have please update me with the case number so that I can have a look at it. Otherwise please open a new ticket with details on the issue and we will investigate.

Hi,

We didn't receive any update about this date 08-03-2015 9:12 AM thread regarding lower chart tooltip position. Please fix this issue in sample application its really very helpful for us.

Thanks,

Hi,

I am glad first issue is fixed now.

I have investigated the crosshair issue and it seems like a lot of factors impact the performance and result in delaying here:

1) The page UI which is heavy to render ( two charts, lots of data, real time animations like the crosshair itself, calculations at lot of events, etc)
2) Adittional crosshair layer that adds up to the heaviness of the UI
3) Two-way binding in Angular

It is really hard to determine a single reason for resulting as it is a result of more than one which adds up. This also makes it hard to introduce a fix rather than general and concrete suggestions on Angular applications performances. I have tried both lowering the complexity of the UI by leaving only a single chart on the page and also removing the aditiional crosshair layer. It essentially improves performance. Considering the above mentioned I suggest:

1) Removing the crosshair layer that is used to remove the horizontal crosshair line
2) Lowering the complexity and density of the UI
3) Best practices on improving performances in Angular:

I hope the above mentioned makes it clear why it is hard to suggest a real fix for this issue, which is in fact a real time animation in an app that takes resources to render complex UI with animations and real time two way binding. The suggested will truly help you improve performance with minimal sacrifice on look and feel and functionality of the charts on the page.

Hi,

Thanks for updating

1. Fixed
2. yes it behave the same way from the beginning. Please fixed this issue as soon as possible we need to deploy this view after this fixing.

Hello,

Please find solutions to your questions below:

1. When we move mouse on chart, values are not rounded on spot its take time to round. How to fix the decimals of all stock prices (open/high/low/close) in pop up to be two digits on spot with out delay ? 

Currently I have been using tooltipShown event, because it is needed for the Date label to be formatted. However it causes this time to display the raw values and the rounded ones. To fix this I separated the logic for the labels and execute it in tooltipShowing for labels and tooltipShown for the Date and Volume label.

This is the fix to display with two digist after separator:

        newRoundedValue = (Math.round(ui.item[labels[i].innerText.slice(0, -1)] * 100) / 100).toFixed(2);
        ui.item[labels[i].innerText.slice(0, -1)] = newRoundedValue;

2. Currently vertical crosshairLayer has a delay following the mouse location. How to make them faster?

I am currently investigating what may be the cause of this issue. Does it behave the same way from the beginning, or do you recall started delaying after introducing a feature or functionality to the sample ?
