Question 1

How to dynamically update a chart in svelte-frappe-charts?

Accepted Answer

Use the addDataPoint or removeDataPoint methods on a chart reference for granular changes, or reassign the entire data prop for full updates, as shown in the README examples with bind:this and event handlers.

Question 2

svelte-frappe-charts vs svelte-chartjs: which should I use?

Accepted Answer

Choose svelte-frappe-charts for a lighter, more Svelte-idiomatic experience with simpler charts; opt for svelte-chartjs if you need more chart types via Chart.js, but expect heavier dependencies and less native integration.

Question 3

Can I export charts as PNG with svelte-frappe-charts?

Accepted Answer

No, the exportChart method only supports SVG export, as per frappe-charts' capabilities. For PNG, you'd need to convert the SVG externally or use a different library with broader export options.

Question 4

How to handle click events on chart elements?

Accepted Answer

Enable the isNavigable prop and listen to the data-select event in your Svelte component, which fires with details on selected data points, allowing custom interaction logic as demonstrated in the navigation demo.

Question 5

Is svelte-frappe-charts compatible with SvelteKit?

Accepted Answer

Yes, it works with SvelteKit as a standard Svelte component, but be mindful of server-side rendering since frappe-charts relies on client-side JavaScript; consider dynamic imports for charts in SSR contexts.

Question 6

What chart types does svelte-frappe-charts support?

Accepted Answer

It supports basic types like line, bar, and pie charts via frappe-charts, but lacks advanced options such as scatter plots or donut charts, so check frappe-charts documentation for the full, limited list.
