nice one, I was thinging there is a way to only see the animation of the last data point
You're right! Animating only the last data point is more efficient and creates a better trading chart experience. Let's modify the chart to focus the animation on just the newest data point:
I've updated the chart to focus animation only on the newest data point, which creates a more realistic trading chart experience. Here's what changed:
Visual Indicators:
isNew flag to each data point to track which one is the newestPerformance Optimization:
isAnimationActive={false})Smoother Experience:
isNew: true and set all other points to isNew: falseCustomDot component only renders for points where isNew is trueThis approach creates a much more realistic trading chart experience where your attention is drawn to just the changing data rather than having the entire chart animate with each update.
The code returns the following error:
FatalRendererError: Cannot read properties of undefined (reading 'isNew')
at CustomDot (/real-time-chart)
Revise the code to address the error.
The error occurs because the CustomDot component is trying to access the isNew property on payload, which might be undefined in some cases. Let's revise the code to handle this situation more gracefully:
These changes should resolve the error you're encountering. Here's a breakdown of what we've done:
CustomDot component, we now check if payload exists before trying to access its isNew property. This prevents the "Cannot read properties of undefined" error.CustomDot and CustomActiveDot components to the dot and activeDot props of the Line and Area components. Instead of passing the component directly, we're now passing a function that renders the component. This ensures that all necessary props are correctly passed to our custom components.These modifications should make the chart more robust and prevent the error you were seeing. The chart should now render correctly and animate only the newest data point as intended.
If you encounter any other issues or have additional requirements, please let me know, and I'll be happy to help further!
The code returns the following error:
A props object containing a "key" prop is being spread into JSX:
let props = {key: someKey, r: ..., stroke: ..., strokeWidth: ..., width: ..., height: ..., fill: ..., index: ..., cx: ..., cy: ..., value: ..., dataKey: ..., payload: ..., points: ...};
<CustomDot {...props} />
React keys must be passed directly to JSX without using spread:
let props = {r: ..., stroke: ..., strokeWidth: ..., width: ..., height: ..., fill: ..., index: ..., cx: ..., cy: ..., value: ..., dataKey: ..., payload: ..., points: ...};
<CustomDot key={someKey} {...props} />
at dot (/real-time-chart)
Revise the code to address the error.
