Chart Prompts

Restyle my chart in the "Scientific Journal" style described below. Keep my data, chart type, title meaning and units; change only the presentation. Use the charting library this project already uses (plain SVG if there is none). If the library can't express a detail, draw it in a custom layer instead of dropping it. Measurements assume a 960 x 600 chart; scale them proportionally.

Mood: a figure from a peer-reviewed paper. Sober, exact and dense with statistical honesty: every mean carries its uncertainty, and the caption does the talking.

Colors (use these exact values):
- Background: #FFFFFF everywhere. No tinted plot area.
- Ink (axes box, ticks, tick labels, axis titles, caption, significance stars): #1A1A1A.
- Reference lines (zero, no-effect): #595959, dashed.
- Series 1 (control, baseline, reference group): #3F3F3F, a near-black gray.
- Series 2 (the treatment or the group the finding is about): #B33A2B, a restrained brick red. This is the only real color. A third series, if unavoidable, is #8C8C8C with a triangle marker; never add another hue.
- Confidence bands: the series color at 16% opacity.

Typography (Google Fonts): STIX Two Text for everything.
- Tick labels 16px regular; axis titles 17px regular in sentence case with the unit in parentheses, e.g. "Escape latency (s)". Use a true minus sign (U+2212) for negative numbers.
- Panel letters: lowercase bold 28px ("a", "b"), top-left, outside the axes box, aligned with its top edge.
- Legend: 16px regular.
- Caption lead-in: bold 18px, "Fig. 2 | " followed by the finding as a full sentence ending in a period.
- Caption body: 16px regular, 25px line spacing, panel references in bold ("a,", "b,"), statistical symbols in italic (n, P, t).

Layout:
- The figure occupies the top ~75% of the canvas; the caption sits below it, left-aligned at x = 40, under a 0.8px #1A1A1A rule spanning the full figure width.
- Where it helps, split the figure into two panels: a wide main panel (about 460px) and a narrower derived panel (about 210px, e.g. difference from control, ratio, or residuals) sharing the x-axis meaning. With a single chart, keep one panel labeled "a".
- Rotated y-axis title centered on the panel height, about 50px left of the axes box. X-axis title centered, 48px below the box.
- The caption carries what would otherwise be a title and subtitle: the bold lead-in states the finding, the body states the measure, what bands and error bars mean, sample size, test used, and ends with "Source: ...".

Axes and grid:
- Fully boxed axes: a closed 1.2px #1A1A1A rectangle around each plot. No gridlines at all.
- Ticks point INWARD on all four sides: major ticks 6px at 1px, minor ticks 3.5px at 0.8px halfway between majors on the y-axis. Top and right ticks mirror bottom and left. Labels only on left and bottom, 9px from the box.
- Pad the x domain by half a step on each side so the first and last points sit inside the box.

Marks:
- Line chart: 2px straight segments (no smoothing) through the means. Markers at every observation: series 1 open circles (r 4.6, white fill, 1.6px stroke), series 2 filled squares (8.8px). Error bars (s.e.m.) as 1.2px vertical lines with 8px caps. A 95% confidence band behind each line, series color at 16% opacity, no outline.
- Bar chart: narrow bars (about 40% of the band) with a 1.2px #1A1A1A outline; series 1 filled white, series 2 filled #B33A2B at 85%. Error bars with caps on every bar, and the individual observations overplotted as small open circles (r 2.5) jittered across the bar.
- Significance: stars (*, **, ***) centered 8px above the upper confidence limit of the highest series at each tested point, 17px. Only star a point whose interval supports it.

Legend: top-right (or whichever corner is empty) inside the axes box, no frame. Each entry is a 30 x 18 px band swatch at 16% opacity with the 2px line and the marker drawn over it, then the label 10px to the right.

Avoid: titles above the figure, gridlines, background fills, gradients, shadows, rounded corners, bold colors, more than two hues, outward ticks, and sans-serif type.

When you're done, render the chart and check that the box is closed with ticks pointing in on all four sides, every mean has a band or error bar, the stars agree with the intervals, and the caption's numbers match the data.
