Chart's PanGesture conflicts with UITableView PanGesture

[carrchr]

I apologize in advance if this issue is more of a Stack Overflow question than a bug/limitation of this framework.
We have a LineChartView in a UITableViewCell subclass in a static UITableView.
Chart is configured like this:

[chart setScaleYEnabled:NO];
[chart setHighlightEnabled:NO];

When the scrolling of tableView finishes decelerating, the PanGesture contained in the LineChart intercepts vertical scrolling and, hence, the containing tableView will not scroll unless you begin a tap/pan outside of the LineChart.
I found private func panGestureRecognized(recognizer: UIPanGestureRecognizer) in BarLineChartViewBase.swift
I am not super familiar with Gesture Recognizers but do I need to change the behavior of this function to handle this scenario?
Thanks!

If you will start dragging again from inside the chart, on a direction which it does not have any more scrolling, it should begin scrolling the parent table view. We cannot seamlessly continue the scroll, as I just haven't yet found a stable way to do that. But the basic functionality of scroll within scroll is there...

I don't quite understand what you mean by scrolling "on a direction
which it does not have any more scrolling." I've disabled YAxis scaling on the chart (XAxis is enabled as is pinch to zoom) and it does not pass a vertical pan gesture up to the containing tableView.
Are you saying I should turn YAxis scaling on and it should work?

Whenever there's no more scrolling on a chart, it will pass control to the
parent view for scrolling. It doesn't matter if scrolling enable or
disabled. Disabled scrolling will just pass control immediately.
When you scroll and reach the end, it will still not scroll the parent. You
have to let go and start scrolling again.

hi, I have similar scenario with you,that,I disable Y axis scale,but I can not scroll vertically tableview in the chart.
I just do a simple hack,that if chart disable Y axis scale,enable UITableView vertically scrolling.

		if !self.isScaleYEnabled {
			_outerScrollView?.nsuiIsScrollEnabled = true
		} else {
			_outerScrollView?.nsuiIsScrollEnabled = false
		}

of BarLineChartViewBase.swift file

Hi, Make the following configuration when configuring the chart
[self.combinedchartview setScaleXEnabled:YES];
[self.combinedchartview setScaleYEnabled:NO];//禁用Y轴缩放
[self.combinedchartview setDragEnabled:YES];

Then modify it in the way you modified it, but the tableview at the bottom of the vertical slide cannot slide
