Difficulty binding JSON data to SyncFusion LineChart

I have been trying to get a simple JSON data consumption to bind to a SyncFusion Line Chart. While I can easily download and parse JSON data in Xamarin for binding to other controls, I cannot get the JSON data to successfully bind to a SyncFusion Line Chart.

My goal is to download stock market price data and bind it to a chart using the LEAST amount of code possible. I want to use the absolute minimal amount of code required to get it working. I can then later add other complexities to it.

I have created a new test solution based off of an example I found for binding JSON data without a POCO object. The solution is pretty simple, but even with the sample data, I cannot get the data to appear. I can see the chart appear, but not the data being plotted.

Eventually I want to replace that sample JSON data with the actual data I am consuming. Here is an EXACT sample of the data that I am consuming:

BEGIN --

[{"date":"2019-08-23","minute":"09:30","label":"09:30 AM","high":46.35,"low":46.31,"open":46.35,"close":46.33,"average":46.333,"volume":1400,"notional":64865.6,"numberOfTrades":12},{"date":"2019-08-23","minute":"09:31","label":"09:31 AM","high":46.3,"low":46.16,"open":46.3,"close":46.17,"average":46.219,"volume":1408,"notional":65076.4,"numberOfTrades":12},{"date":"2019-08-23","minute":"09:32","label":"09:32 AM","high":46.23,"low":46.14,"open":46.185,"close":46.14,"average":46.174,"volume":1900,"notional":87730.5,"numberOfTrades":17},{"date":"2019-08-23","minute":"09:33","label":"09:33 AM","high":46.23,"low":46.16,"open":46.16,"close":46.2,"average":46.201,"volume":801,"notional":37007.2,"numberOfTrades":9},{"date":"2019-08-23","minute":"09:34","label":"09:34 AM","high":46.32,"low":46.265,"open":46.265,"close":46.32,"average":46.298,"volume":273,"notional":12639.345,"numberOfTrades":3},{"date":"2019-08-23","minute":"09:35","label":"09:35 AM","high":46.325,"low":46.23,"open":46.325,"close":46.235,"average":46.289,"volume":1701,"notional":78737.81,"numberOfTrades":12},{"date":"2019-08-23","minute":"09:36","label":"09:36 AM","high":46.185,"low":46.125,"open":46.185,"close":46.125,"average":46.164,"volume":693,"notional":31992.01,"numberOfTrades":12}]

END ---

I just want to plot the "minute" and "close" properties of this data on the chart.

Below is the example I created based off of a sample I found. I want to replace the JSONDATA found in this example with the data above. However, when I retrieve my actual stock data, it doesn't have the "\" keystroke before each quote (as you can see above). I don't know how to work around that. Be that as it may, here is the code below I have created, yet even with this I cannot get the X and Y values to actually plot. I'm not seeing what I am missing, although I'm sure it's probably simple.

Any advice is greatly appreciated. Here is my sample:
