# How do I refine, iterate, and export a chart?

{% hint style="info" %}
**What this article covers** This article explains how to modify a chart after it has been generated, iterate on it using natural language follow-up prompts, and export it for use in presentations or publications.
{% endhint %}

When K-Pro returns a chart or visualisation, it is fully interactive — you are not locked into the initial result. You can refine, filter, or re-format it simply by typing a follow-up instruction in the chat.

### How to iterate on a chart

After a chart is generated, type a follow-up instruction in the chat to modify it. K-Pro understands context from the previous message, so you do not need to repeat the full prompt.

{% hint style="success" %}
**Iteration prompt examples:**

* "Filter this plot to only show stage III patients"
* "Split by EGFR mutation status"
* "Change the colour palette to be colour-blind friendly"
* "Remove the outliers and re-plot"
* "Add a statistical significance annotation"
* "Show the same data as a violin plot instead of a box plot"
  {% endhint %}

### How to export a chart

Once you are satisfied with a chart, you can download it for use in presentations, reports, or publications:

1. Hover over the chart in the K-Pro interface.
2. Click the **download icon** (or the ⋮ menu) that appears in the top-right corner of the chart.
3. Select your preferred format: **PNG** (for presentations) or **SVG** (for publication-quality vector graphics).

{% hint style="warning" %}
**Troubleshooting:** If the download icon is not visible, try hovering directly over the chart area. On some browsers, the icon only appears on hover. If the issue persists, try a different browser or submit a support request.
{% endhint %}

### Tips for better charts

* **Start specific**: name the gene, dataset, cancer type, and chart type in your first prompt for the most relevant first result.
* **Iterate progressively**: one change at a time works better than combining multiple instructions in a single follow-up.
* **Reference "this chart" or "this plot"** in follow-up prompts so K-Pro knows you are modifying the existing result rather than starting a new analysis.
