I'm a little confused here. So, the code snippet above is exactly what's
used to initialize the data currently.
The expected behavior is that the graph should start from the right side
only. However, currently, when the page loads, for a few seconds, the
graphs are visible on the left side and then shift to the right.
I think we can skip the reverse if we make changes in the statsReducer
method.
action.counter ? action.incoming[label] - action.counterData[label] :
action.incoming[label],
...state[label].slice(0, X_AXIS_LENGTH-1),
Here, we are adding new data to the beginning and selecting the first
X_AXIS_LENGTH-1 datapoints from the previous state. However, an alternative
approach would be to initially take the X_AXIS_LENGTH-1 elements from the
end of the array, then add a new element to the end. This would eliminate
the need to reverse the array.
I believe this reversal isn't causing any issues, but something might be
occurring during graph plotting. Reversing just ensures that the most
recent data point remains on the right within the stream.
Thank you,
Sahil
