xmatthias opened a new issue #15809: URL: https://github.com/apache/echarts/issues/15809
### Version 5.2.1 ### Steps to reproduce Provide a series with booleans as input. The chart will render these fine (usign 1 / 0 as values). The tooltip will however show `seriesname -`. This used to work in older versions, and seems to be a regression introduced in either 5.1 or 5.2 series. <details> <summary>reproduction code</summary> Copy of [the echarts sample](https://echarts.apache.org/examples/en/editor.html?c=candlestick-sh) with slight modifications to create a boolean series. Simply pasting the below code into the samples editor and hovering over the series will display the problem. ``` js const upColor = '#ec0000'; const upBorderColor = '#8A0000'; const downColor = '#00da3c'; const downBorderColor = '#008F28'; // Each item: open，close，lowest，highest const data0 = splitData([ ['2013/1/24', 2320.26, 2320.26, 2287.3, 2362.94], ['2013/1/25', 2300, 2291.3, 2288.26, 2308.38], ['2013/1/28', 2295.35, 2346.5, 2295.35, 2346.92], ['2013/1/29', 2347.22, 2358.98, 2337.35, 2363.8], ['2013/1/30', 2360.75, 2382.48, 2347.89, 2383.76], ['2013/1/31', 2383.43, 2385.42, 2371.23, 2391.82], ['2013/2/1', 2377.41, 2419.02, 2369.57, 2421.15], ['2013/2/4', 2425.92, 2428.15, 2417.58, 2440.38], ['2013/2/5', 2411, 2433.13, 2403.3, 2437.42], ['2013/2/6', 2432.68, 2434.48, 2427.7, 2441.73], ['2013/2/7', 2430.69, 2418.53, 2394.22, 2433.89], ['2013/2/8', 2416.62, 2432.4, 2414.4, 2443.03], ['2013/2/18', 2441.91, 2421.56, 2415.43, 2444.8], ['2013/2/19', 2420.26, 2382.91, 2373.53, 2427.07], ['2013/2/20', 2383.49, 2397.18, 2370.61, 2397.94], ['2013/2/21', 2378.82, 2325.95, 2309.17, 2378.82], ['2013/2/22', 2322.94, 2314.16, 2308.76, 2330.88], ['2013/2/25', 2320.62, 2325.82, 2315.01, 2338.78], ['2013/2/26', 2313.74, 2293.34, 2289.89, 2340.71], ['2013/2/27', 2297.77, 2313.22, 2292.03, 2324.63], ['2013/2/28', 2322.32, 2365.59, 2308.92, 2366.16], ['2013/3/1', 2364.54, 2359.51, 2330.86, 2369.65], ['2013/3/4', 2332.08, 2273.4, 2259.25, 2333.54], ['2013/3/5', 2274.81, 2326.31, 2270.1, 2328.14], ['2013/3/6', 2333.61, 2347.18, 2321.6, 2351.44], ['2013/3/7', 2340.44, 2324.29, 2304.27, 2352.02], ['2013/3/8', 2326.42, 2318.61, 2314.59, 2333.67], ['2013/3/11', 2314.68, 2310.59, 2296.58, 2320.96], ['2013/3/12', 2309.16, 2286.6, 2264.83, 2333.29], ['2013/3/13', 2282.17, 2263.97, 2253.25, 2286.33], ['2013/3/14', 2255.77, 2270.28, 2253.31, 2276.22], ['2013/3/15', 2269.31, 2278.4, 2250, 2312.08], ['2013/3/18', 2267.29, 2240.02, 2239.21, 2276.05], ['2013/3/19', 2244.26, 2257.43, 2232.02, 2261.31], ['2013/3/20', 2257.74, 2317.37, 2257.42, 2317.86], ['2013/3/21', 2318.21, 2324.24, 2311.6, 2330.81], ['2013/3/22', 2321.4, 2328.28, 2314.97, 2332], ['2013/3/25', 2334.74, 2326.72, 2319.91, 2344.89], ['2013/3/26', 2318.58, 2297.67, 2281.12, 2319.99], ['2013/3/27', 2299.38, 2301.26, 2289, 2323.48], ['2013/3/28', 2273.55, 2236.3, 2232.91, 2273.55], ['2013/3/29', 2238.49, 2236.62, 2228.81, 2246.87], ['2013/4/1', 2229.46, 2234.4, 2227.31, 2243.95], ['2013/4/2', 2234.9, 2227.74, 2220.44, 2253.42], ['2013/4/3', 2232.69, 2225.29, 2217.25, 2241.34], ['2013/4/8', 2196.24, 2211.59, 2180.67, 2212.59], ['2013/4/9', 2215.47, 2225.77, 2215.47, 2234.73], ['2013/4/10', 2224.93, 2226.13, 2212.56, 2233.04], ['2013/4/11', 2236.98, 2219.55, 2217.26, 2242.48], ['2013/4/12', 2218.09, 2206.78, 2204.44, 2226.26], ['2013/4/15', 2199.91, 2181.94, 2177.39, 2204.99], ['2013/4/16', 2169.63, 2194.85, 2165.78, 2196.43], ['2013/4/17', 2195.03, 2193.8, 2178.47, 2197.51], ['2013/4/18', 2181.82, 2197.6, 2175.44, 2206.03], ['2013/4/19', 2201.12, 2244.64, 2200.58, 2250.11], ['2013/4/22', 2236.4, 2242.17, 2232.26, 2245.12], ['2013/4/23', 2242.62, 2184.54, 2182.81, 2242.62], ['2013/4/24', 2187.35, 2218.32, 2184.11, 2226.12], ['2013/4/25', 2213.19, 2199.31, 2191.85, 2224.63], ['2013/4/26', 2203.89, 2177.91, 2173.86, 2210.58], ['2013/5/2', 2170.78, 2174.12, 2161.14, 2179.65], ['2013/5/3', 2179.05, 2205.5, 2179.05, 2222.81], ['2013/5/6', 2212.5, 2231.17, 2212.5, 2236.07], ['2013/5/7', 2227.86, 2235.57, 2219.44, 2240.26], ['2013/5/8', 2242.39, 2246.3, 2235.42, 2255.21], ['2013/5/9', 2246.96, 2232.97, 2221.38, 2247.86], ['2013/5/10', 2228.82, 2246.83, 2225.81, 2247.67], ['2013/5/13', 2247.68, 2241.92, 2231.36, 2250.85], ['2013/5/14', 2238.9, 2217.01, 2205.87, 2239.93], ['2013/5/15', 2217.09, 2224.8, 2213.58, 2225.19], ['2013/5/16', 2221.34, 2251.81, 2210.77, 2252.87], ['2013/5/17', 2249.81, 2282.87, 2248.41, 2288.09], ['2013/5/20', 2286.33, 2299.99, 2281.9, 2309.39], ['2013/5/21', 2297.11, 2305.11, 2290.12, 2305.3], ['2013/5/22', 2303.75, 2302.4, 2292.43, 2314.18], ['2013/5/23', 2293.81, 2275.67, 2274.1, 2304.95], ['2013/5/24', 2281.45, 2288.53, 2270.25, 2292.59], ['2013/5/27', 2286.66, 2293.08, 2283.94, 2301.7], ['2013/5/28', 2293.4, 2321.32, 2281.47, 2322.1], ['2013/5/29', 2323.54, 2324.02, 2321.17, 2334.33], ['2013/5/30', 2316.25, 2317.75, 2310.49, 2325.72], ['2013/5/31', 2320.74, 2300.59, 2299.37, 2325.53], ['2013/6/3', 2300.21, 2299.25, 2294.11, 2313.43], ['2013/6/4', 2297.1, 2272.42, 2264.76, 2297.1], ['2013/6/5', 2270.71, 2270.93, 2260.87, 2276.86], ['2013/6/6', 2264.43, 2242.11, 2240.07, 2266.69], ['2013/6/7', 2242.26, 2210.9, 2205.07, 2250.63], ['2013/6/13', 2190.1, 2148.35, 2126.22, 2190.1] ]);

``` </details> ### What is expected? Rendering should display either `seriesname 1` or `seriesname true` instead of `seriesname -`. ### What is actually happening? `seriesname -` is displayed <!-- This issue is generated by echarts-issue-helper.
