[Question] Any known good charting library

[polderudo]

We are using unipdf to create some realy nice looking PDF reports. The only thing we are really missing a a nice charting library. There does not seem to be anything good lokking stuff for go out there.

go-echarts looks realy nice, but there is no way to extract the image (using js internaly) https://github.com/wcharczuk/go-chart is also good for the stuff it does, but it does not realy include much chart types. https://github.com/gonum/plot is the library that we use now mostly, because it has plety of different charts.

Except go-echarts they all look very academical and the output is not good for beeing used in real reports.

Do you at unidoc know of a good library out there? Commercial or free

Welcome! Thanks for posting your first issue. The way things work here is that while customer issues are prioritized, other issues go into our backlog where they are assessed and fitted into the roadmap when suitable. If you need to get this done, consider buying a license which also enables you to use it in your commercial products. More information can be found on https://unidoc.io/

Hi @polderudo Yes, those are both widely used. Are you not able to style them to your needs? Would be helpful to get a concrete example if what you are looking for, some examples. So we can look further into this.

@polderudo We have created our own vectorized graphic library UniChart which can be used for graphs. We based it on https://github.com/wcharczuk/go-chart but extended for generating vectorized output, and more graph formats. Would be great to get some feedback on it.

For example of a good example using it with report templates, see: https://github.com/unidoc/unipdf-examples/tree/master/templates/security-report
