Add API to get chart values (data, markers, etc)

Why is there no getPrice? or getMarkers();

Would really like them, makes it much easyer for me to use.

Example: This is how I need to get the current price now: let currentPrice = Array.from(Array.from(priceArea._dataUpdatesConsumer.de.ee)[priceArea._dataUpdatesConsumer.de.ee.size - 1][1].mapping)[0][1].value;

Just write getPrice(); would make it much more easyer and would have saved me at least 3 hours of searching.

Again, you should use number at series’ value, toFixed() function returns a string, obviously it’s not gonna work. If you really wanna round up your numbers, try Math.round() instead.

No offence, but I think your major problem is with javascript, you don’t seem to understand the primitive types and having a lot of trouble writing your code in an efficient way. Thus, many of your issues might be caused by that instead of this library.

This is kind of off topic I assumed, yet I suggest you write in Typescript (which is a superset of javascript) to check these potential errors, since this library is written in Typescript the first place and it will very much improve your coding experience by providing better code completion and type checks.

greenLine.setMarkers([
   {
         time: 2020-4-22,            //This works, but adds a marker to the beginning of the line where the date/time is 2019-4-11.
         position: 'aboveBar',
         color: '#42f54b',
         shape: 'arrowDown',
         text: 'Current price: ' + movingAveragePrice,
         id: 'first',
   },
   {
         time: '2020-4-23',          //This does not work. And does not even show anything.
         position: 'belowBar',
         color: '#f54242',
         shape: 'arrowUp',
         text: 'Current price: ' + movingAveragePrice,
         id: 'second',
   }
]);

It might be just me doing something wrong but I didn’t add such alot of weird things. Just used the normal functions of your library without any other library/plugin or anything included. If I indeed did nothing wrong (which I strongly think) then this is where the real ISSUE is comming to pass.

Well, you basically did everything wrong in this part…

In your code, 2020-4-22 literally means 2020 - 4 - 22 = 1994, which is an integer and will be considered as an UNIX timestamp. And for the second marker, '2020-4-23' should be '2020-04-23' to follow the ISO format of YYYY-MM-DD.

Docs of lightweight-charts might not be great, but definitely good enough to make things running.
