[Question]: Change chart focus and change histogram width

[AbcoldQAQ]

I would like to ask how to open the chart so that the focus is on the midpoint instead of the rightmost point (I use it to draw the liquidity distribution chart of virtual currency), and how to change the width of each column of the Histogram chart

Hi, @AbcoldQAQ! Thank you for the question!

Can you elaborate more on this part I would like to ask how to open the chart so that the focus is on the midpoint instead of the rightmost point (I use it to draw the liquidity distribution chart of virtual currency)? Do you mean crosshair position or am i wrong?

Regarding the second part of your question: this can be done via custom series plugin for lightweight-charts. You can see some examples here. But ideally i would like to recommend you to address this question to the maintainers of the core library - https://github.com/tradingview/lightweight-charts/issues.

So, if you go "custom plugin" way you can later use CustomSeries component to render the plugin on the chart, like here

And i would recommend you not to create the plugin from scratch, there are definitely already created solutions to change the width of columns.
