Adding a legend to a chart.

[stolk]

So I am using a chart with many lines in it.
Now I want to label the colours, and also give them a toggle.

How can I have the labels in the checkbox use the same color as the lines? Is there a quick way to color either the foreground or background of a label, or a checkbox?

void Overlay::DrawStats(void)
{
    if ( !m_economy)
        return;

    nk_context* ctx = static_cast<nk_context*>(m_context);

    const int opts =
        NK_WINDOW_BORDER |
        NK_WINDOW_MOVABLE |
        NK_WINDOW_MINIMIZABLE |
        NK_WINDOW_NO_SCROLLBAR |
        NK_WINDOW_SCALABLE |
        NK_WINDOW_TITLE;

    struct nk_color colours[] =
    {
        nk_rgb(0,122,183),
        nk_rgb(255,113,0),
        nk_rgb(0,166,29),
        nk_rgb(251,0,27),
        nk_rgb(163,98,192),
        nk_rgb(158,80,72),
        nk_rgb(128,128,128),
        nk_rgb(190,191,0),
        nk_rgb(0,197,209),
    };
    const int winW = 320;
    const int winH = 400;
    const int winX = 16;
    const int winY = m_screenHeight - winH - 16;
    SetFont(F_SANS_REGULAR);
    if (nk_begin(ctx, "Economy", nk_rect(winX, winY, winW, winH), opts))
    {
        SetFont(F_MONO_SYSTEM);
        nk_layout_row_dynamic(ctx, 200, 1);
        const int hsz = m_economy->HistorySize();
        const int head = m_economy->m_hist_head;
        const int nump = 6;
        if ( hsz>2 )
        {
            if ( nk_chart_begin_colored(ctx, NK_CHART_LINES, colours[0], nk_rgb(0,0,0), hsz, -1, 50) )
            {
                for ( int p=2; p<nump; ++p )
                    nk_chart_add_slot_colored(ctx, NK_CHART_LINES, colours[p-1], nk_rgb(0,0,0), hsz, -1, 50);

                for ( int i=0; i<hsz; ++i )
                {
                    const int idx = ( head + i ) & HISTMASK;
                    for ( int p=1; p<nump; ++p )
                    {
                        int val = m_economy->m_productionhistory[idx][p];
                        nk_chart_push_slot(ctx, val, p-1);
                    }
                }
            }
        }
        nk_layout_row_dynamic(ctx, 20, 5);
        static int vals[5] = {1,1,1,1,1};
        nk_checkbox_label(ctx, prodnames[1], vals+0);
        nk_checkbox_label(ctx, prodnames[2], vals+1);
        nk_checkbox_label(ctx, prodnames[3], vals+2);
        nk_checkbox_label(ctx, prodnames[4], vals+3);
        nk_checkbox_label(ctx, prodnames[5], vals+4);
    }
    nk_end(ctx);
}

Look at the following sections in nuklear.h:

/* =============================================================================
 *
 *                                  STYLE
 *
 * ============================================================================= */

/* =============================================================================

 *                                  COLOR
